At one time, we thought that the way life came together was almost completely random, only needing an energy gradient to get going. But as we’ve moved into the information age, we’ve come to realize that life is more about information than energy. Fire has most of the characteristics of life. It eats, it grows, it reproduces. But fire retains no information. It doesn’t learn; it doesn’t adapt. The five millionth fire started by lightning will behave just like the first. But the five hundredth bacterial division will not be like the first one, especially if there is environmental pressure. That’s DNA. And RNA. That’s life. …

Matter and energy are equivalent, according to the equation E=mc2, where E stand for energy, m for mass and c for the speed of light,' 'Merapa explained. 'Matter can't be transported at the speed of light but energy can. Therefore, during a time shift transformation, matter is converted to energy then condenses back. In other words all the molecules in your body have been changed from matter to energy then back again.' 'Wow. It's a wonder it's not fatal,' Dirck said. 'Sometimes it is. If any transcription errors occur between the DNA and RNA in your vital organs you're all but dead.

But she became more interested in DNA’s less-celebrated sibling, RNA. It’s the molecule that actually does the work in a cell by copying some of the instructions coded by the DNA and using them to build proteins.

Biovirus TA TA TA targets organisms, hacking and reprogramming ATGACTTATCCACGGTACATTCAGT cellular DNA to produce more virus virus virus virus virus virus virus virus. Its enzymic cut-and-past recombinant wetware-splicing crosses singularity when retroviral reverse-transcriptase clicks in (enabling ontogenetic DNA-RNA circuitry and endocellular computation).

A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.

This overall flow of genetic information—from DNA to RNA to protein—is known as the central dogma of molecular biology, and it is the language used to communicate and express life.

how a piece of RNA could pair up with its phage DNA counterpart and cause that DNA to be destroyed.

RNA (ribonucleic acid) is a molecule in living cells that is similar to DNA (deoxyribonucleic acid), but it has one more oxygen atom in its sugar-phosphate backbone and a difference in one of its four bases.

Apart from a few viruses, all life on Earth now relies on DNA to hold the information that it needs to reproduce. But the most likely players in the first games of life were molecules of the related genetic material RNA, which is more flexible than DNA because it can both carry information down the generations and also catalyze—speed up—chemical reactions, a very handy feat. And RNA still carries out all kinds of critical roles in organisms that are described by DNA, including human beings.

A small segment of DNA that encodes a gene is transcribed into a snippet of RNA, which then travels to the manufacturing region of the cell. There this “messenger RNA” facilitates the assembly of the proper sequence of amino acids to make a specified protein.

It also showed that the only real block to bi-maternal reproduction is the DNA methylation pattern at key genes. It disproved a previous hypothesis that sperm were required because the sperm themselves carried certain necessary accessory factors such as particular proteins or RNA molecules required to kick-start development properly.16

When the genetic code was solved, in the early 1960s, it turned out to be full of redundancy. Much of the mapping from nucleotides to amino acids seemed arbitrary—not as neatly patterned as any of Gamow’s proposals. Some amino acids correspond to just one codon, others to two, four, or six. Particles called ribosomes ratchet along the RNA strand and translate it, three bases at a time. Some codons are redundant; some actually serve as start signals and stop signals. The redundancy serves exactly the purpose that an information theorist would expect. It provides tolerance for errors. Noise affects biological messages like any other. Errors in DNA—misprints—are mutations.

Here I should issue a caveat. In origins-of-life research (and probably in most other disciplines as well), scientists gravitate to models that highlight their personal scientific specialty. Organic chemist Stanley Miller and his cohorts saw life’s origins as essentially a problem in organic chemistry. Geochemists, by contrast, have tended to focus on more intricate origins scenarios involving such variables as temperature and pressure and chemically complex rocks. Experts in membrane-forming lipid molecules promote the “lipid world,” while molecular biologists who study DNA and RNA view the “RNA world” as the model to beat. Specialists who study viruses, or metabolism, or clays, or the deep biosphere have their idiosyncratic prejudices as well. We all do it; we all focus

Nature isn’t benign,” Lederberg said at the meeting’s opening. “The bottom lines: the units of natural selection—DNA, sometimes RNA elements—are by no means neatly packaged in discrete organisms. They all share the entire biosphere. The survival of the human species is not a preordained evolutionary program. Abundant sources of genetic variation exist for viruses to learn new tricks, not necessarily confined to what happens routinely, or even frequently.

Kısa bir süre sonra bakteri savunma sisteminin en az iki kritik bileşen içerdiği anlaşıldı. Bunlardan birincisi ''arayıcı'' idi - virüsün DNA'sıyla örtüşerek tanıyan bakteri RNA'sı. Bu tanıma ilkesi de hayret vericiydi: ''Arayıcı'' RNA, virüs DNA'sının ayna görüntüsüydü - yin ve yang gibi. Böylece istilacı virüsün DNA'sını fark edebiliyordu. Düşmanın resmini sürekli cebinde taşır gibi veya bakteri örneğinde, düşmanın resminin negatifini genomunda taşır gibi.

In the late 1970s, scientists working on gene-silencing discovered that the attachment of a small molecule-a methyl group-to DNA was correlated with a gene's turning off. These methyl tags decorated the strands of DNA, like charms on a necklace, and they were recognized as shutdown signals. The production of RNA ceased and the expression of the gene was silenced. If a chromosome was heavily decorated by methyl tags, then perhaps the whole chromosome could be silenced.

The word epigenetics literally means “above the gene.” It refers to the control of genes not from within the DNA itself but from messages coming from outside the cell—in other words, from the environment. These signals cause a methyl group (one carbon atom attached to three hydrogen atoms) to attach to a specific spot on a gene, and this process (called DNA methylation) is one of the main processes that turns the gene off or on. (Two other processes, covalent histone modification and noncoding RNA, also turn genes on and off,

Viruses are just single strands of RNA or DNA lying around. They can’t replicate until and unless they find a cell to hijack. So they aren’t alive, but they also aren’t not alive. Once a virus invades a cell, it does what life does—it uses energy to make more of itself. Viruses remind me that life is more of a continuum than a duality. Sure, viruses aren’t living, because they need host cells to replicate. But then again, many bacteria also can’t survive without hosts, and stranger still, many hosts can’t survive without bacteria.

Genetik kod basittir: DNA'dan RNA inşa edilir, RNA'dan da protein inşa edilir. DNA'daki her baz üçlüsü, proteinde bir aminoasidi belirler. Oysa genomik kod karmaşıktır: Genin üzerinde, genin ne zaman ve nerede ifade edileceği ile ilgili bilgileri barındıran DNA parçaları vardır: Genlerin genom üzerindeki yerlerinin neye göre belirlenmiş olduğunu da bilmiyoruz. Genler arasındaki DNA bölgelerinin gen fizyolojisini nasıl düzenlediğini ve koordine ettiğini de bilmiyoruz. Dağların ötesinde dağların olması gibi, kodların ötesinde de kodlar vardır.

What is that 95 percent? Some is junk—remnants of pseudogenes inactivated by evolution.fn4,3 But buried in that are the keys to the kingdom, the instruction manual for when to transcribe particular genes, the on/off switches for gene transcription. A gene doesn’t “decide” when to be photocopied into RNA, to generate its protein. Instead, before the start of the stretch of DNA coding for that gene is a short stretch called a promoterfn5—the “on” switch. What turns the promoter switch on? Something called a transcription factor (TF) binds to the promoter. This causes the recruitment of enzymes that transcribe the gene into RNA. Meanwhile, other transcription factors deactivate genes.

Why has DNA had a monopoly on molecular symbolism over the past few hundreds of millions of years? In its physical manifestation, DNA is extremely structurally stable, unlike RNA. This has helped DNA remain the symbolic structure of choice throughout evolution. However, while the DNA in our cells and the cells of other living organisms is now very stable, the structure of DNA did not start out that way at the very origins of life. Random shuffling and re-sorting of molecules, through the irreversible and probabilistic process of natural selection, generated molecules resembling nucleotide bases. Through subsequent shuffling, successful DNA components and sequences survived and replicated.

Genes, oddly, compromise only a minuscule fraction of it. An enormous proportion-a bewildering 98 percent-is not dedicated to genes per se, but to enormous stretches of DNA that are interspersed between genes (intergenic DNA) or within genes (introns). These long stretches encode no RNA, and no protein: they exist in the genome either because they regulate gene expression, or for reasons that we do not yet understand, or because of no reason whatsoever (i.e., they are "junk" DNA). If the genome were a line stretching across the Atlantic Ocean between North America and Europe, genes would be occasional specks of land strewn across long, dark tracts of water. Laid end to end, these specks would be no longer than the largest Galapagos island or a train line across the city of Tokyo,

During replication, those nucleotides are read and translated into linear strings of amino acids (which make up enzymes and proteins) by a rule-governed process. The set of rules is called the genetic code. The DNA contains the sequence, but the code is implemented by RNA molecules. Certain DNA sequences, called codons, which are made up of three nucleotides, symbolize certain amino acid sequences. There is no ambiguity, but there is also not just one codon for each amino acid. For example, six different codons symbolize arginine, but only one codon symbolizes tryptophan. But the components of the DNA sequence (the symbol) do not resemble the components of the amino acid sequence (its meaning), just as the words that symbolize the components of a recipe do not resemble the components themselves.

The third cardinal feature of gene regulation, Monod and Jacob discovered, was that every gene had specific regulatory DNA sequences appended to it that acted like recognition tags. Once a sugar sensing-protein had detected sugar in the environment, it would recognize one such tag and turn the target genes on or off. That was a gene's signal to make more RNA messages and thereby generate the relevant enzyme to digest the sugar. A gene, in short, possessed not just information to encode a protein, but also information about when and where to make that protein. All that data was encrypted in DNA, typically appended to the front of every gene (although regulatory sequences) an also be appended to the ends and middle of genes). The combination of regulatory sequences and the protein-encoding sequence defined a gene.

The DNA-RNA apparatus isn't the whole secret of life, but a sort of computer program by which the real secret, the control system, ex-presses its pattern in terms of living cells.This pattern is part of what many people mean by the soul, which somany philosophies have tried to explicate. However, most of the pro-posed answers haven't been connected with the physical world of biology in a way that offered a toehold for experiment. Like many attempts, the latest major scientific guess, the morphogenetic field proposed by Paul Weiss in 1939, was just a restatement of the problem, though a useful one. Weiss conjectured that development was guided by some sort of field projected from the fertilized egg. As the dividing cell mass became an embryo and then an adult, the field changed its shape and somehow led the cells onward.

How does the body push the comparatively tiny genome so far? Many researchers want to put the weight on learning and experience, apparently believing that the contribution of the genes is relatively unimportant. But though the ability to learn is clearly one of the genome's most important products, such views overemphasize learning and significantly underestimate the extent to which the genome can in fact guide the construction of enormous complexity. If the tools of biological self-assembly are powerful enough to build the intricacies of the circulatory system or the eye without requiring lessons from the outside world, they are also powerful enough to build the initial complexity of the nervous system without relying on external lessons. The discrepancy melts away as we appreciate the true power of the genome. We could start by considering the fact that the currently accepted figure of 30,000 could well prove to be too low. Thirty thousand (or thereabouts) is, at press time, the best estimate for how many protein-coding genes are in the human genome. But not all genes code for proteins; some, not counted in the 30,000 estimate, code for small pieces of RNA that are not converted into proteins (called microRNA), of "pseudogenes," stretches of DNA, apparently relics of evolution, that do not properly encode proteins. Neither entity is fully understood, but recent reports (from 2002 and 2003) suggest that both may play some role in the all-important process of regulating the IFS that control whether or not genes are expressed. Since the "gene-finding" programs that search the human genome sequence for genes are not attuned to such things-we don't yet know how to identify them reliably-it is quite possible that the genome contains more buried treasure.

A virus particle is a very small capsule made of proteins locked together in a mathematical pattern. The pattern of the interlocking proteins in a virus is far more complicated than a snowflake. The protein capsule is sometimes wrapped in an oily membrane. Inside the capsule there is a small amount of DNA or RNA, the molecules that contain the genetic code of the virus. The genetic code is the virus’s operating system, or wetware, the complete set of instructions for the virus to make copies of itself. Unlike a snowflake or any other kind of crystal, a virus is able to re-create its form. It would be as if a single snowflake started copying itself as it falls, and those copies of the snowflake copy themselves, creating ever-growing numbers of identical copies of the first snowflake, until the air is filled with falling snow, and each flake is a perfect replica of the first flake.

Recently scientists have found that cephalopods (the family that contains the octopus) can recode their RNA. RNA molecules have the privilege of establishing codes with DNA (in the part of the RNA that recognizes the three-nucleotide DNA codon sequence) and also with proteins (in the separate part of the RNA that recognizes the amino acid). Recoding the RNA means that new proteins can be constructed while the DNA sequence of symbols stays the same. The collective result is the destruction of the one-to-one gene-to-protein correspondence. Recoding allows a single octopus gene to produce many different types of proteins from the same DNA sequence.18 This is a big deal. It is evidence against the three concepts in biology that dismiss semiotic systems in living organisms. The system can change its code. The system has an internal codemaker that can produce biological innovations—new proteins—but not via natural selection. It illustrates the arbitrariness of the connection of a symbol with its meaning in a living system. If symbols within living systems

The bacterial defense system was soon found to involve at least two critical components. The first piece was the "seeker"-an RNA encoded in the bacterial genome that matched and recognized the DNA of the viruses. The principle for the recognition, yet again, was binding: the RNA "seeker" was able to find and recognize the DNA of an invading virus because it was a mirror image of that DNA-the yin to its yang. It was like carrying a permanent image of your enemy in your pocket-or, in the bacteria's case, an inverted photograph, etched indelibly into its genome. The second element of the defense system was the "hitman." Once the viral DNA had been recognized and matched as foreign (by its reverse-image), a bacterial protein named Cas9 was deployed to deliver the lethal gash to the viral gene. The "seeker" and the "hitman" worked in concert: the Cas9 protein delivered its cuts to the genome only after the sequence had been matched by the recognition element. It was a classic combination of collaborators-spotter and executor, drone and rocket, Bonnie and Clyde.

Flagyl was clearly effective in the treatment of Lyme disease. But how did it work? As early as 1967 The British Journal of Venereal Diseases had published a study showing Flagyl to be effective in certain cases of syphilis, and that it had an effect on bacterial DNA and RNA irrespective of bacterial replication. Could this be the mechanism of Flagyl’s action against Burrelia burgdorferi? The key to Flagyl’s effectiveness on Lyme, however, was not reported until several months after my study was presented. Dr. O. Brorson, a Norwegian researcher, published a paper on Flagyl and its effect on the cystic forms of Lyme disease six months after I presented my research. The cystic form of Lyme disease, it turns out, is one mechanism that Borrelia burgdorferi utilizes to persist in the body. Dr. Brorson reported that Flagyl would cause Borrelia cysts to rupture, and he went on to publish that he could see under the microscope the cell wall forms of Borrelia burgdorferi (helical/spiral–shaped organisms) transform into cystic forms, and under proper conditions convert back into mobile spirochetes. A review of the medical literature revealed that these cystic forms had, in fact, been reported in syphilis. No one had clearly made the link between Borrelia and a cystic form of the organism that could persist for long periods of time in a dormant state. It was a highly evolved survival mechanism that would allow the organism to reemerge when conditions were optimal. My patient, Mary, had been treated initially with Plaquenil, which according to Dr. Brorson’s research also affects the cystic forms, yet it appeared that it was not powerful enough to destroy the dormant forms and prevent a relapse, or to prevent her from passing it on to her fetus. She had also been treated with drugs that addressed the cell wall and intracellular forms of Lyme. Although Plaquenil has some effect on cystic forms, it is often primarily used in antibiotic regimens with Lyme disease to alkalize the intracellular compartment, modulate autoimmune reactions, and affect essential enzymes necessary for bacterial replication. Clearly, however, it is not powerful enough to destroy enough of the

It was the magnesium. The addition of the ion was critical: with the solution supplemented with magnesium, the ribosome remained glued together, and Brenner and Jacob finally purified a miniscule amount of the messenger molecule out of bacterial cells. It was RNA, as expected-but RNA of a special kind. The messenger was generated afreah when a gene was translated. Like DNA, these RNA molecules were built by stringing together four bases-A,G,C, and U (in the RNA copy of a gene, remember, the T found in DNA is substituted for U). Notably, Brenner and Jacob later discovered the messenger RNA was a facsimile of the DNA chain-a copy made from the original. The RNA copy of a gene then moved from the nucleus to the cytosol, where its message was decoded to build a protein. The messenger RNA was neither an inhabitant of heaven nor of hell-but a professional go-between. The generation of an RNA copy of a gene was termed transcription-referring to the rewriting of a word or sentence in a language close to the original. A gene's code (ATGGGCC...) was transcribed into an RNA code (AUGGGCC...).

Working independently, Baltimore and Temin discovered an enzyme found in retroviruses that could build DNA from an RNA template. They called the enzyme reverse transcriptase-"reverse" because it inverted the normal direction of information flow: from RNA back to DNA, or from a gene's message backward to a gene, thereby violating Crick's "central dogma" (that genetic information only moved from genes to messages, but never backward). Using reverse transcriptase, ever RNA in a cell could be used as a template to build its corresponding gene. A biologist could thus generate a catalog, or "library" of all "active" genes in a cell-akin to a library of books grouped by subject. There would be a library of genes for T cells and another for red blood cells, a library for neurons in the retina, for insulin-secreting cells of the pancreas, and so forth. By comparing libraries derived from two cells-a T cell and a pancreas cell, say-an immunologist could fish out genes that were active in one cell and not the other (e.g., insulin or the T cell receptor). Once identified, that gene could be amplified a millionfold in bacteria. The gene could be isolated and sequenced, its RNA and protein sequence determined, its regulatory regions identified; it could be mutated an inserted into a different cell to decipher the gene's structure and function. In 1984 this technique was deployed to clone the T cell receptor-a landmark achievement in immunology.

As an anology, consider the word structure. In bacteria, the gene is embedded in the genome in precisely that format, structure, with no breaks, stuffers, interpositions, or interruptions. In the human genome, in contrast, the word is interrupted by intermediate stretches of DNA: s...tru...ct...ur...e. The long stretches of DNA marked by the ellipses (...) do not contain any protein-encoding information. When such an interrupted gene is used to generate a message-i.e., when DNA is used to build RNA-the stuffer frragments are excised from the RNA message, and the RNA is stitched together again with the intervening pieces removed: s...tru...ct...ur...e became simplified to structure. Roberts and Sharp later coined a phrase for the process: gene splicing or RNA splicing (since the RNA message of the gene was "spliced" to removed the stuffer fragments). At first, this split structure of genes seemed puzzling: Why would an animal genome waste such long stretches of DNA splitting genes into bits and pieces, only to stitch them back into a continuous message? But the inner logic of split genes soon became evident: by splitting genes into modules, a cell could generate bewildering combinations of messages out of a single gene. The word s...tru...c...t...ur...e can be spliced to yield cure and true and so forth, thereby creating vast numbers of variant messages-called isoforms-out of a single gene. From g...e...n...om...e you can use splicing to generate gene, gnome, and om. And modular genes also had an evolutionary advantage: the individual modules from different genes could be mixed and matched to build entirely new kinds of genes (c...om...e...t). Wally Gilbert, the Harvard geneticist, created a new word for these modules; he called them exons. The inbetween stuffer fragments were termed introns.

A virus particle is a very small capsule made of proteins locked together in a mathematical pattern. The pattern of the interlocking proteins in a virus is far more complicated than a snowflake. The protein capsule is sometimes wrapped in an oily membrane. Inside the capsule there is a small amount of DNA or RNA, the molecules that contain the genetic code of the virus.

Many virologists feel that viruses are not truly living things. At the same time, viruses are obviously not dead. Virologists like to describe them as life forms. The term is a contradiction: How can something be a form of life that isn’t alive? Viruses carry on their existence in a misty borderland that lies between life and death, a gray zone where the things we encounter are neither provably alive nor certainly dead. One way to understand viruses is to think about them as biological machines. A virus is a wet nanomachine, a tiny, complicated, slightly fuzzy mechanism, which is rubbery, flexible, wobbly, and often a little bit imprecise in its operation—a microscopic nugget of squishy parts. Viruses are subtle, logical, tricky, reactive, devious, opportunistic. They are constantly evolving, their forms steadily changing as time passes. Like all kinds of life, viruses possess a relentless drive to reproduce themselves so that they can persist through time. When a virus starts copying itself strongly and rapidly in a host, the process is called virus amplification. As a virus amplifies itself in its host, the host, a living organism, can be destroyed. Viruses are the undead of the living world, the zombies of deep time. Nobody knows the origin of viruses—how they came into existence or when they appeared in the history of life on earth. Viruses may be examples or relics of life forms that operated at the dawn of life. Viruses may have come into existence with the first stirrings of life on the planet, roughly four billion years ago. Or they may have arisen after life started, during the time when single-celled bacteria had already come into existence—nobody knows.

Although we fully understand the genetic code-i.e., how the information in a single gene is used to build a protein-we comprehend virtually nothing of the genomic code-i.e., how multiple genes spread across the human genome coordinate gene expression in space and time to build, maintain, and repair a human organism. The genetic code is simple: DNA is used to build RNA, and RNA is used to build a protein. A triplet of bases in DNA specifies one amino acid in the protein. The genomic code is complex: appended to a gene are sequences of DNA that carry information on when and where to express the gene. We do not know why certain genes are located in particular geographic locations in the genome, and how the tracts of DNA that lie between genes regulate and coordinate gene physiology. There are codes beyond codes, like mountains beyond mountains.

Consider how the principles of the law of accelerating returns apply to the epochs we discussed in the first chapter. The combination of amino acids into proteins and of nucleic acids into strings of RNA established the basic paradigm of biology. Strings of RNA (and later DNA) that self-replicated (Epoch Two) provided a digital method to record the results of evolutionary experiments. Later on, the evolution of a species that combined rational thought (Epoch Three) with an opposable appendage (the thumb) caused a fundamental paradigm shift from biology to technology (Epoch Four). The upcoming primary paradigm shift will be from biological thinking to a hybrid combining biological and nonbiological thinking (Epoch Five), which will include “biologically inspired” processes resulting from the reverse engineering of biological brains.

life’s business in a fundamentally different way—using a molecule other than DNA or RNA as genetic material, for example, or a different set of amino acids to build proteins.

that it was fantastically easy to target specific genes. All you had to do was select the desired twenty-letter DNA sequence to edit and then convert that sequence into a matching twenty-letter code of RNA. Once inside the cell, the RNA would couple with its DNA match using base pairing, and Cas9 would slice apart the DNA.

Some scientists also credit viruses with creating DNA in the first place (from RNA) billions of years ago, and they argue that viruses still invent most new genes today.

If the adaptor hypothesis were true (and it was), this meant that the role of DNA and RNA would be reduced to simply carrying genetic information: they had no direct structural role as templates; they were merely a medium

Man with all his noble qualities still bears in his bodily frame the indelible stamp of his lowly origin.

Duality is particularly widespread within biological order, from the ‘base-pairs’ of (RNA and) DNA code, through the binary fission of bacterial propagation, the (binary) sexual difference of meiotic reproduction, to the bilateral symmetry of the typical vertebrate organism with consequent pairing of limbs (arms, legs), sense-organs (eyes, ears), lungs, brain-hemispheres, etc. ‘Dual-organization’ provides a basic model for primordial human kinship structure.

First in importance are the nucleic acids, DNA and RNA, which contain the genetic information, the software of life.

Atoms, elements and molecules are three important knowledge in Physics, chemistry and Biology. mathematics comes where counting starts, when counting and measurement started, integers were required. Stephen hawking says integers were created by god and everything else is work of man. Man sees pattern in everything and they are searched and applied to other sciences for engineering, management and application problems. Physics, it is required understand the physical nature or meaning of why it happens, chemistry is for chemical nature, Biology is for that why it happened. Biology touch medicine, plants and animals. In medicine how these atoms, elements and molecules interplay with each other by bondage is being explained. Human emotions and responses are because of biochemistry, hormones i e anatomy and physiology. This physiology deals with each and every organs and their functions. When this atom in elements are disturbed whatever they made i e macromolecules DNA, RNA and Protein and other micro and macro nutrients and which affects the physiology of different organs on different scales and then diseases are born because of this imbalance/ disturb in homeostasis. There many technical words are there which are hard to explain in single para. But let me get into short, these atoms in elements and molecules made interplay because of ecological stimulus i e so called god. and when opposite sex meets it triggers various responses on body of each. It is also harmone and they are acting because of atoms inside elements and continuous generation or degenerations of cell cycle. There is a god cell called totipotent stem cell, less gods are pluripotent, multi potent and noni potent stem cells. So finally each and every organ system including brain cells are affected because of interplay of atoms inside elements and their bondages in making complex molecules, which are ruled by ecological stimulus i e god. So everything is basically biology and medicine even for animals, plants and microbes and other life forms. process differs in each living organisms. The biggest mystery is Brain and DNA. Brain has lots of unexplained phenomenon and even dreams are not completely understood by science that is where spiritualism/ soul touches. DNA is long molecule which has many applications as genetic engineering. genomics, personal medicine, DNA as tool for data storage, DNA in panspermia theory and many more. So everything happens to women and men and other sexes are because of Biology, Medicine and ecology. In ecology every organisms are inter connected and inter dependent. Now physics - it touch all technical aspects but it needs mathematics and statistics to lay foundation for why and how it happened and later chemistry, biology also included inside physics. Mathematics gave raise to computers and which is for fast calculation on any applications in any sciences. As physiological imbalances lead to diseases and disorders, genetic mutations, again old concept evolution was retaken to understand how new biology evolves. For evolution and disease mechanisms, epidemiology and statistics was required and statistics was as a data tool considered in all sciences now a days. Ultimate science is to break the atoms to see what is inside- CERN, but it creates lots of mysterious unanswerable questions. laws in physics were discovered and invented with mathematics to understand the universe from atoms. Theory of everything is a long search and have no answers. While searching inside atoms, so many hypothesis like worm holes and time travel born but not yet invented as far as my knowledge. atom is universe, and humans are universe they have everything that universe has. ecology is god that affects humans and climate. In business these computerized AI applications are trying to figure out human emotions by their mechanism of writing, reading, texting, posting on social media and bla bla. Arts is trying to figure out human emotions in art way.

The actual mechanics of cell division, according to Dick McIntosh at the University of Denver, require significantly more instructions than it takes to build a moon rocket or supercomputer. First of all, the cell needs to duplicate all of its molecules, that is DNA, RNA, proteins, lipids, etc. At the organelle level, several hundred mitochondria, large areas of ER, new Golgi bodies, cytoskeletal structures, and ribosomes by the million all need to be duplicated so that the daughter cells have enough resources to grow and, in turn, divide themselves. All these processes make up the ‘cell cycle’. Some cells will divide on a daily basis, others live for decades without dividing. The cell cycle is divided into phases, starting with interphase, the period between cell divisions (about 23 hours), and mitosis (M phase), the actual process of separating the original into two daughter cells (about 1 hour). Interphase is further split into three distinct periods: gap 1 (G1, 4–6 hours), a synthesis phase (S, 12 hours), and gap 2 (G2, 4–6 hours). Generally, cells continue to grow throughout interphase, but DNA replication is restricted to the S phase. At the end of G1 there is a checkpoint. If nutrient and energy levels are insufficient for DNA synthesis, the cell is diverted into a phase called G0. In 2001 Tim Hunt, Paul Nurse, and Leeland Hartwell received the Nobel Prize for their work in discovering how the cell cycle is controlled. Tim Hunt found a set of proteins called cyclins, which accumulate during specific stages of the cell cycle. Once the right level is reached, the cell is ‘allowed’ to progress to the next stage and the cyclins are destroyed. Cyclins then start to build up again, keeping a score of the progress at each point of the cycle, and only allowing progression to the next stage if the correct cyclin level has been reached.

Although the nucleus might have been recognized by Antonie van Leeuwenhoek in the late 17th century, it was not until 1831 that it was reported as a specific structure in orchid epidermal cells by a Scottish botanist, Robert Brown (better known for recognizing ‘Brownian movement’ of pollen grains in water). In 1879, Walther Flemming observed that the nucleus broke down into small fragments at cell division, followed by re-formation of the fragments called chromosomes to make new nuclei in the daughter cells. It was not until 1902 that Walter Sutton and Theodor Boveri independently linked chromosomes directly to mammalian inheritance. Thomas Morgan’s work with fruit flies (Drosophila) at the start of the 20th century showed specific characters positioned along the length of the chromosomes, followed by the realization by Oswald Avery in 1944 that the genetic material was DNA. Some nine years later, James Watson and Francis Crick showed the structure of DNA to be a double helix, for which they shared the Nobel Prize in 1962 with Maurice Wilkins, whose laboratory had provided the evidence that led to the discovery. Rosalind Franklin, whose X-ray diffraction images of DNA from the Wilkins lab had been the key to DNA structure, died of cancer aged 37 in 1958, and Nobel Prizes are not awarded posthumously. Watson and Crick published the classic double helix model in 1953. The final piece in the jigsaw of DNA structure was produced by Watson with the realization that the pairing of the nucleotide bases, adenine with thymine and guanine with cytosine, not only provided the rungs holding the twisting ladder of DNA together, but also provided a code for accurate replication and a template for protein assembly. Crick continued to study and elucidate the base pairing required for coding proteins, and this led to the fundamental ‘dogma’ that ‘DNA makes RNA and RNA makes protein’. The discovery of DNA structure marked an enormous advance in biology, probably the most significant since Darwin’s publication of On the Origin of Species .

Infrared light therapy stimulates production of collagen, ribonucleic acid (RNA), ATP, and deoxyribonucleic acid (DNA), which enhances the body’s cellular repair rejuvenation systems, providing relief from pain and shortening recovery time.

Life, as we know it on earth, appears as a synthesis of two macromolecular systems. The proteins, because of their versatility and chemical reactivity, do all the work but are unable to replicate themselves in any simple way. The nucleic acids seem tailor-made for replication but can achieve rather little else compared with the more elaborate and better equipped proteins. RNA and DNA are the dumb blondes of the biomolecular world, fit mainly for reproduction (with a little help from proteins) but of little use for much of the really demanding work. The problem of the origin of life would be a great deal easier to approach if there were only one family of macromolecules, capable of doing both jobs, replication and catalysis, but life as we know it employs two families. This may well be due to the fact that no macromolecule exists which could conveniently carry out both functions, because of the limitations of organic chemistry; because, that is, of the nature of things.

Most mutations appear to be a result  of mineral deficiencies. A deficiency  in one or two minerals causes a mutation in the DNA. When this mutation occurs, the message that the DNA gives to the RNA is also faulty. This explains why arthritic cells and irritable bowel cells, to name just a few, continue to be made. The RNA must  have the necessary minerals to complete the protein. O'Neill, Barbara . Self Heal By Design- The Role Of Micro-Organisms For Health By Barbara O'Neill (p. 59).

The Air ncRNA gave scientists important insights into how these long ncRNAs repress gene expression. The ncRNA remained localised to a specific region in the cluster of imprinted genes, and acted as a magnet for an epigenetic enzyme called G9a. G9a puts a repressive mark on the histone H3 proteins in the nucleosomes deposited on this region of DNA. This histone modification creates a repressive chromatin environment, which switches off the genes.

ncRNAs have recently been implicated in Lamarckian transmission of inherited characteristics. In one example, fertilised mouse eggs were injected with a miRNA which targeted a key gene involved in growth of heart tissue. The mice which developed from these eggs had enlarged hearts (cardiac hypertrophy) suggesting that the early injection of the miRNA disturbed the normal developmental processes. Remarkably, the offspring of these mice also had a high frequency of cardiac hypertrophy. This was apparently because the abnormal expression of the miRNA was recreated during generation of sperm in these mice. There was no change in the DNA code of the mice, so this was a clear case of a miRNA driving epigenetic inheritance

Pharmaceutical companies became very interested in using siRNAs as potential new drugs. Theoretically, siRNA molecules could be used to knock down expression of any protein that was believed to be harmful in a disease. In the same year that Fire and Mello were awarded their Nobel Prize, the giant pharmaceutical company Merck paid over one billion US dollars for a siRNA company in California called Sirna Therapeutics. Other large pharmaceutical companies have also invested heavily. But in 2010 a bit of a chill breeze began to drift through the pharmaceutical industry. Roche, the giant Swiss company, announced that it was stopping its siRNA programmes, despite having spent more than $500 million on them over three years. Its neighbouring Swiss corporation, Novartis, pulled out of a collaboration with a siRNA company called Alnylam in Massachusetts. There are still plenty of other companies who have stayed in this particular game, but it would probably be fair to say there’s a bit more nervousness around this technology than in the past. One of the major problems with using this kind of approach therapeutically may sound rather mundane. Nucleic acids, such as DNA and RNA, are just difficult to turn into good drugs. Most good existing drugs – ibuprofen, Viagra, anti-histamines – have certain characteristics in common. You can swallow them, they get across your gut wall, they get distributed around your body, they don’t get destroyed too quickly by your liver, they get taken up by cells, and they work their effects on the molecules in or on the cells. Those all sound like really simple things, but they’re often the most difficult things to get right when developing a new drug. Companies will spend tens of millions of dollars – at least – getting this bit right, and it is still a surprisingly hit-and-miss process. It’s so much worse when trying to create drugs around nucleic acids. This is partly because of their size. An average siRNA molecule is over 50 times larger than a drug like ibuprofen. When creating drugs (especially ones to be taken orally rather than injected) the general rule is, the smaller the better. The larger a drug is, the greater the problems with getting high enough doses into patients, and keeping them in the body for long enough. This may be why a company like Roche has decided it can spend its money more effectively elsewhere. This doesn’t mean that siRNA won’t ever work in the treatment of illnesses, it’s just quite high risk as a business venture.

Only 2 per cent of our genome codes for proteins. A massive 42 per cent is composed of retrotransposons. These are very odd sequences of DNA, which probably originated from viruses in our evolutionary past. Some retrotransposons are transcribed to produce RNA and this can affect the expression of neighbouring genes. This can have serious consequences for cells. If it drives up expression of genes that cause cells to proliferate too aggressively, for example, this may nudge cells towards becoming cancerous.

The energies of the electromagnetic spectrum include microwaves, radio waves, x-rays, extremely low-frequency waves, sound harmonic frequencies, ultraviolet rays, and even infrared waves. Specific frequencies of electromagnetic energy can influence the behavior of DNA, RNA, and protein synthesis; alter protein shape and function; control gene regulation and expression; stimulate nerve-cell growth; and influence cell division and cell differentiation, as well as instruct specific cells to organize into tissues and organs. All of these cellular activities influenced by energy are part of the expression of life. And

Virüsler kısaca zorunlu hücre içi parazitleridirler. Yaygın bilimsel kanıya ve modern canlılık tanımlarına göre "canlı olmayan; ancak canlılığın eşiğinde olan varlıklar" olarak tanımlanmaktadır. Bölünerek çoğalmazlar, çoğalmak için konak hücresini ve enzimlerini kullanırlar. Canlı hücreyi enfekte etme yeteneği taşıyan ergin virüse virion adı verilir. Bazı virüsler evrimsel süreçlerindeki mutasyonlar sonucu kendi kendilerine çoğalamazlar. Sadece kendilerine akraba olan virüslerin varlığında çoğalabilirler. Bu tür virüslere Defektif Virüsler adı veriliyor. Yine bazı virüsler kendi kendilerine replike olamazlar ancak akraba olmayan herhangi bir virüs eşliğinde çoğalabilirler. Bu tür virüslere de Uydu (Satelit) Virüsler deniliyor. Virüsler bakteriyolojik boyalarla boyanmazlar, ışık mikroskobunda görülemeyecek kadar küçüktürler, hücresel organeller içermezler ve antibiyotiklerden etkilenmezler. Sadece interferon (vücut hücrelerinde sentezlenen, virüsün protein yapımını inhibe eden proteinler) ve antiviral yöntemlerle durdurulabilirler. Bazı özel replikasyon enzimleri (RNA bağımlı RNA polimeraz, Ters Transkriptaz) gibi çok az sayıda enzim içerebilirler.  Morfoloji ve kimyasal özellikleri eşsizdir. Nükleik asitleri ya (tek/çift iplik) DNA ya da (tek/çift iplik) RNA'dan oluşur. DNA ve RNA beraber bulunmaz. En içerde nükleik asit ve onu saran, koruyan, morfolojisini veren kapsid (kılıf) bulunur. Bütün virüsler kendi kapsid proteinlerini kodlarlar. Kapsidi oluşturan alt ünitelere kapsomer, kapsomerleri oluşturan polipeptid zincirleri şeklindeki alt ünitelere de protomer adı verilir. Kapsomerler, virüse antijenik özellik kazandırır. Viral kapsidin aynı protein alt birimlerinden oluşmasının avantajları, genetik bilgi ihtiyacı az olması ve herhangi bir enzim veya enerji gereksinimi olmadan kendi kendine bir araya toplanabilir olmasıdır. Kapsid, ikozahedral (kübik simetri) ya da helikal (sarmal simetri) şeklinde bulunabilir. Ancak sadece RNA virüslerinde kapsid, helikal yapıdadır. Çünkü helikal yapılı kapsidler sadece RNA'yı paketleyebilir. Ayrıca insanlarda hastalık oluşturan bütün helikal simetrili virüsler zarflıdır ve RNA içerir. Nükleik asit ve kapsidin tamamına da nükleokapsid adı verilir.  Nükleokapsidden dışa doğru gidildikçe bazı virüslerde zarf adı verilen glikoprotein/lipoprotein bir membran bulunur. Ancak zarfsız virüsler, zarflılara göre sinsi ve tehlikelidir. Çünkü kolay yayılırlar. Kurumaya, mide-bağırsak yoluna, antikorlara, deterjan ve diğer kimyasallara dayanıklıdırlar. Zarflı virüslerde zarf ile kapsid arasında kalan bölgeye tegument (matrix) denir. Bazı büyük virüslerde bu bölgede konak hücreden aldığı bazı proteinleri depo edebilir. Zarf yapısında bulunan virüse özgü glikoprotein birimlere de peplomer adı verilir. Ayrıca bazı virüslerin dış kısmında transmembran glikoproteinler bulunur. Temel görevleri konak hücreye yapışma ve sızmadır. Örneğin: F proteini, füzyon ve hemolitik (eritositleri parçalayan) etki yapar. Nöraminidaz, hücre reseptörlerinde bulunan korunmayı sağlayan oligosakkaritlerin siyalik asit yapısını parçalar. Grip virüsü (influenza) gibi bazı virüslerin yüzeyinde hemaglütinin denen antikor molekülü de eritrositleri kümeleştirir. Tıpta bu özellik tanı için kullanılır.  Küçük virüslerin genomları 3-4 genden oluşurken, Pox gibi büyük virüslerde bu sayı 200-300 geni bulabilir. Retrovirüsler hariç genomları haploiddir. Genomun yapısı düz (lineer), çembersel (sirküler) ya da parçalı (segmenter) olabilir. Ancak çift iplikli DNA virüsleri sadece düz veya çembersel formda olabilir. Parçalı yapıda bulunamaz. Tek veya çift iplikli DNA/RNA'nın bir de polaritesi (kutuplaşan elektriksel yükü) vardır. 3' ucundan 5' ucuna ise negatif polariteli, 5' ucundan

all life forms, no matter how diverse, have common characteristics: 1) they are made up of cells, enclosed by a membrane that maintains internal conditions different from their surroundings, 2) they contain DNA or RNA as the material that carries their master plan, and 3) they carry out a process, called metabolism, which involves the conversion of different forms of energy by means of which they sustain themselves.

W 1965 roku sekwencjonowanie rybosomalnego RNA 5S pochodzącego z bakterii (koszty sekwencjonowania RNA i DNA są podobne) kosztowało tysiąc funtów na parę zasad. W 1975 roku sekwencjonowanie DNA wirusa X174 kosztowało około 10 funtów na parę zasad. Hodgkin nie znalazł odpowiedniego przykładu z 1985 roku, ale dziesięć lat później sekwencjonowanie DNA nicienia Caenorhabditis elegans kosztowało 1 funta na parę zasad. Nawiasem mówiąc, ten maleńki obleniec cieszy się wielką (i zasłużoną) sympatią biologów molekularnych, którzy mówią o nim „nasz” obleniec albo nawet „nasz” robak[XXIV].

For that matter, how do we switch from simple chemical affiliations to selection for proteins? And how do we get from RNA to DNA? As it happens, there are some striking answers, backed up by surprising findings in the last few years. Gratifyingly, the new findings square beautifully with the idea of life evolving in hydrothermal vents, the setting of Chapter 1.

But while DNA is meant to last forever, all RNA is temporary. It serves a specific purpose, then is broken down by the cell.

The most fundamental objection to Gamow’s scheme is that it does not distinguish between the direction of a sequence; that is, between Thr. Pro. Lys. Ala. and Ala. Lys. Pro. Thr…. There is little doubt that Nature makes this distinction, though it might be claimed that she produces both sequences at random, and that the “wrong” ones—not being able to fold up—are destroyed. This seems to me unlikely. That observation, made in passing, was the first acknowledgment of a theoretical question that is still unanswered: in general terms, what does the cell do with information it possesses on the DNA—and some organisms possess some DNA sequences in thousands of copies—that it does not use to code for proteins? This difficulty brings us face-to-face with one of the most puzzling features of the DNA structure—the fact that it is non-polar, due to the dyads at the side; or put another way, that one chain runs up while the other runs down. It is true that this only applies to the backbone, and not to the base sequence, as Delbrück has emphasized to me in correspondence. This may imply that a base sequence read one way makes sense, and read the other way makes nonsense. Another difficulty is that the assumptions made about which diamonds are equivalent are not very plausible…. [Gamow’s idea] would not be unreasonable if the amino acid could fit on to the template from either side, into cavities which were in a plane, but the structure certainly doesn’t look like that. The bonds seem mainly to stick out perpendicular to the axis, and the template is really a surface with knobs on, and presents a radically different aspect on its two sides…. What, then are the novel and useful features of Gamow’s ideas? It is obviously not the idea of amino acids fitting on to nucleic acids, nor the idea of the bases sequence of the nucleic acids carrying the information. To my mind Gamow has introduced three ideas of importance: (1) In Gamow’s scheme several different base sequences can code for one amino acid…. This “degeneracy” seems to be a new idea, and, as discussed later, we can generalise it. (2) Gamow boldly assumed that code would be of the overlapping type…. Watson and I, thinking mainly about coding by hypothetical RNA structures rather than by DNA, did not seriously consider this type of coding. (3) Gamow’s scheme is essentially abstract. It originally paid lip service to structural considerations, but the position was soon reached when “coding” was looked upon as a problem in itself, independent as far as possible of how things might fit together…. Such an approach, though at first sight unnecessarily abstract, is important. Finally it is obvious to all of us that without our President the whole problem would have been neglected and few of us would have tried to do anything about it.

none of which, from their point of view, had the least thing to do with DNA, RNA, and proteins, or with carbon, oxygen, hydrogen, and nitrogen, or with photons, electrons, protons, and neutrons, let alone with quarks, gluons, W and Z bosons, gravitons, and Higgs particles.

By the 1960s, Howard Temin had determined that retrovirus genomes were composed of RNA, and observed that replication was inhibited by actinomycin D, which inhibits DNA synthesis, and led to the proposal of the concept of reverse transcription. In 1969, Huebner and Todaro proposed the viral oncogene hypothesis – namely, the transmission of viral and oncogenic information as genetic elements, rather than as a pathogenic response to a virus. David Baltimore at MIT independently replicated Temin’s work, and the pair published a joint article in Nature on June 27, 1970 that described their discoveries. And in 1981, the

This archetypal circuit is replete with what Jung called synchronicities — meaningful coincidences — which he attributed to the circuit’s roots in what he called the “psychoid” level, below the personal and collective unconscious, where “mind” and "matter” are not yet differentiated — the royal highway of the DNA-RNA-CNS (central nervous system) telegraph, in Tim Leary’s metaphor.

The DNA is made up of two opposite spirals, positive and negative, which can easily be considered isomorphic to I Ching's yin () and yang (), or Leibniz's 0 and 1, or Joyce's and . These are bonded by four amino acids—adenine, guanine, cytosine and thymine, which are usually abbreviated A, G, C, T. If one dares to consider these isomorphic with active yang (), passive yang (), active yin () and passive yin (), or Leibniz's 01,11,10 and 00, or Joyce's and , then the parallel becomes staggering. In forming RNA messages—the genetic code—the T (thymine) drops out to be replaced by U (uracil) but we still have four elements—A, G, C, U—and if we permutate them by the now-familiar rule, making all possible combinations of three out of these basic four "letters," we get again 43 or 64 "words," which are the 64 elements of the genetic language.

The sixth circuit of the brain kicks into action when the nervous system begins to receive signals from within the individual neuron — from the RNA-DNA “dialogue,” the neurogenetic feedback system.

The entire nervous system, including the brain, has been designed like the rest of the body, by the “code” within the DNA molecule, which sends signals via messenger RNA molecules to tell the organism what to do: Grow red hair. Have blue eyes. Stand up and walk now. Start to talk. Find a mate. Etc. Our entire mental lives — our brain hardware and software — exist within the perimeters of this DNA master-tape.

RNA could generate DNA. A cancer-causing virus’s genome could become a physical part of a cell’s genes.

Since the mid-1990s, the focus of research in mental illness has shifted from psychological studies, which analyze behaviors, to genetics and the study of chemicals in the brain (DNA, RNA, and proteins).

The skeptical and frequently hostile reactions to prions from many precincts of the scientific community reflected resistance to a profound change in thinking. Prions were seen as an anomaly: they reproduce and infect but contain no genetic material—neither DNA nor RNA; thus they constitute a disruptive transition in our understanding of the biological world.

That the protein failed to bind on double-stranded DNA when it had succeeded in binding on single-stranded RNA was not, however, a “silly mistake.” It was the undesired result of a hypothesis-driven experiment. A failure, yes, but an intelligent failure—and an inevitable part of the fascinating work of science. Most important, that failure would inform the next experiment.

Years ago, however, with the development of lipid nanoparticles (LNPs), molecules were found that could act as brain-penetrating packaging material; that is, they could cross the blood-brain barrier. Their original use was to deliver chemotherapeutic drugs to the brain for the treatment of brain tumors (see sidebar Brain Toxic Packaging).37 It was no secret that LNPs could also be used to deliver genetic material in the form of DNA or mRNA to the brain or brain cells to become biologically active.

In DNA, the alphabetic instructions are adenine, thymine, cytosine, and guanine. One way to recognize mRNA in the cell is that it does not contain thymine, but substitutes uracil instead. The mRNA is then composed of a collection of these four bases (a, u, c, and g). It takes only three bases to form what is called a “codon.” This codon corresponds to an amino acid. A large protein called a ribosome works like a tiny machine, moving along the mRNA strand, while transfer RNA (tRNA) units attach, encoding one of twenty amino acids. The string of amino acids form into a protein.[353]

The amount of DNA not coding for RNA, sometimes called junk DNA (a dangerous term for something one does not understand), is also much greater in eukaryotes.

Absolutely! Retroviruses essentially inject single-stranded RNA strands into somatic (body) cells during “infection.” These ssRNA strands access nucleotide pools in the host cell and form a double-stranded DNA copy.

In most life forms, genes are stretched out along the length of a filament-like molecule of DNA, deoxyribonucleic acid. But many viruses—including influenza, HIV, and the coronavirus that causes SARS (severe acute respiratory syndrome)—encode their genes in RNA, ribonucleic acid, an even simpler but less stable molecule.

The other theory argues that replication based on nucleic acids (RNA and/or DNA) came after biological entities could support metabolism. Günter Wächtershäuser proposed a version of this metabolism-first theory in which hot water from volcanoes flowed over mineral-rich rocks to ignite (catalyze) chemical reactions that fused simple carbon-based compounds into larger ones. While catalytic enzymes, which are proteins, did not yet exist, minerals, such as those in rocks, can and do function as prebiotic catalysts for chemical reactions. According to this theory, a key step occurred when, through a series of these prebiotic reactions, the circle was closed by the regeneration of the original compound. Through such a process, complex biological molecules (proteins, nucleotides, lipids, and carbohydrates) could be made, forming the basis of simple protocells that made energy and replicated.

how does DNA control RNA? The structure of DNA must at least give us a hint.

In the standard Darwinian view, for evolution to occur, you need genetic material (DNA or RNA), and you need a random or chance mutation in this genetic material in an extremely rare form that is not lethal—because virtually all of them are—and further, one that actually contributes to the organism’s capacity to successfully reproduce. This also means that you need this same incredibly rare mutation (or a series of them) to occur in a male organism and a female organism simultaneously, and—even more unlikely—they have to find each other and then mate.

These increases in brain cholesterol and pituitary activity were clues that were rich in their implications, and in the late 1960’s a research team at the University of California at Berkeley began to look for specific differences in the neural structures of gentled and ungentled rats. They found that greater tactile stimulation resulted in the following differences: These animals’ brains were heavier, and in particular they had heavier and thicker cerebral cortexes. This heaviness was not due only to the presence of more cholesterol—that is, more myeline sheaths—but also to the fact that actual neural cell bodies and nuclei were larger. Associated with these larger cells were greater quantities of cholinesterase and acetylcholinesterase, two enzymes that support the chemical activities of nerve cells, and also a higher ratio of RNA to DNA within the cells. Increased amounts of these specific compounds indicates higher metabolic activity. Measurements of the synaptic junctions connecting nerve cells revealed that these junctions were 50% larger in cross-section in the gentled rats than in the isolated ones. The gentled rats’ adrenal glands were also markedly heavier, evidence that the pituitary-adrenal axis—the most important monitor of the body’s hormonal secretions—was indeed more active.34 Many other studies have confirmed and added to these findings. Laboratory animals who are given rich tactile experience in their infancy grow faster, have heavier brains, more highly developed myelin sheaths, bigger nerve cells, more advanced skeletal muscular growth, better coordination, better immunological resistance, more developed pituitary/adrenal activity, earlier puberties, and more active sex lives than their isolated genetic counterparts. Associated with these physiological advantages are a host of emotional and behavioral responses which indicate a stronger and much more successfully adapted organism. The gentled rats are much calmer and less excitable, yet they tend to be more dominant in social and sexual situations. They are more lively, more curious, more active problem solvers. They are more willing to explore new environments (ungentled animals usually withdraw fearfully from novel situations), and advance more quickly in all forms of conditioned learning exercises.35 Moreover, these felicitous changes are not to be observed only in infancy and early maturation; an enriched environment will produce exactly the same increases in brain and adrenal weights and the same behavioral changes in adult animals as well, even though the adults require a longer period of stimulation to show the maximum effect.36

specific genes. All you had to do was select the desired twenty-letter DNA sequence to edit and then convert that sequence into a matching twenty-letter code of RNA. Once inside the cell, the RNA would couple with its DNA match using base pairing, and Cas9 would slice apart the DNA.

The combination of amino acids into proteins and of nucleic acids into strings of RNA established the basic paradigm of biology. Strings of RNA (and later DNA) that self-replicated (Epoch Two) provided a digital method to record the results of evolutionary experiments. Later on, the evolution of a species that combined rational thought (Epoch Three) with an opposable appendage (the thumb) caused a fundamental paradigm shift from biology to technology (Epoch Four). The upcoming primary paradigm shift will be from biological thinking to a hybrid combining biological and nonbiological thinking (Epoch Five), which will include “biologically inspired” processes resulting from the reverse engineering of biological brains.

It is utterly remarkable how science comes up with new names and equations to describe Self. Self easily gets lost in translation which is why Self ended up with The Tower of Babel. First science tells Human it is not God but Physical this although Physical means Spiritual (Physic=Spirit). Naturally this is insufficient for, although Human no longer believes it is God, Human still believes in God. Not to be discouraged, science comes up with the DNA world hypothesis which suggests that Life on Earth began with DNA this although DNA is Deus Non Alligator (Spirit Unbound). Now Human ends up further in the rabbit hole it itself is digging. There is a lot of confusion by now but science wants to keep going which is reminiscent of the story of Hansel and Gretel leaving bread crumbs along the trail and getting lost in translation. So it is. The moment Human questions the concept of DNA science returns to Human with RNA and sells Human the RNA world hypothesis which suggests that Life on Earth began with a simple RNA molecule that could copy itself without help from other molecules stating DNA, RNA, and proteins are central to Life on Earth. Clever clever! Of course RNA is an invention for the meaning of the word RNA is Ram Non Alligator. Ram naturally being Rama also known as Ramachandra (रामचन्द्र, Rāmacandra) which is a major deity of Hinduism being the 7th avatar of the God Vishnu. What is next? VNA? KNA? CNA? GNA? INA? My G-dness. Let I tell I itself is I and let's just return to the indivisible nature of I. I is pure spirit. I is indivisible. I is Love. Love is the purpose of Life for Life is not Life but God desiring not to be alOne, desiring companionship, desiring Love! I does not say all sciences are incorrect but it is true that some in the sciences seem to be pulling their own leg, woof woof I-ndeed. Nothing wrong with T(h)āt as long as तत् does not forget the purpose of its own beingness: Love! Interestingly enough; the meaning of the word Hypothesis means Less Than God. As such; return to God is Love One eternally must. The equation? God=Love.

Like a strand of DNA, the mRNA is a chain of letters, and its sequence matches the sequence of the DNA it copied (the only major exception being that T gets replaced by U). The mRNA is exported out of the cell’s nucleus and delivered to a protein-synthesizing factory called a ribosome, which translates the four-letter language of RNA (A, G, C, and U) into the twenty-letter language of proteins (the twenty amino acids). This translation proceeds according to the genetic code, a cipher in which every three-letter RNA combination, called a codon, instructs the ribosome to add one specific amino acid.

New York Times article from March 8, 1953, titled “Looking Back Two Billion Years.” “Obviously,” Edmond said, “this experiment raised some eyebrows. The implications could have been earth-shattering, especially for the religious world. If life magically appeared inside this test tube, we would know conclusively that the laws of chemistry alone are indeed enough to create life. We would no longer require a supernatural being to reach down from heaven and bestow upon us the spark of Creation. We would understand that life simply happens…as an inevitable by-product of the laws of nature. More importantly, we would have to conclude that because life spontaneously appeared here on earth, it almost certainly did the same thing elsewhere in the cosmos, meaning: man is not unique; man is not at the center of God’s universe; and man is not alone in the universe.” Edmond exhaled. “However, as many of you may know, the Miller-Urey experiment failed. It produced a few amino acids, but nothing even closely resembling life. The chemists tried repeatedly, using different combinations of ingredients, different heat patterns, but nothing worked. It seemed that life—as the faithful had long believed—required divine intervention. Miller and Urey eventually abandoned their experiments. The religious community breathed a sigh of relief, and the scientific community went back to the drawing board.” He paused, an amused glimmer in his eyes. “That is, until 2007…when there was an unexpected development.” Edmond now told the tale of how the forgotten Miller-Urey testing vials had been rediscovered in a closet at the University of California in San Diego after Miller’s death. Miller’s students had reanalyzed the samples using far more sensitive contemporary techniques—including liquid chromatography and mass spectrometry—and the results had been startling. Apparently, the original Miller-Urey experiment had produced many more amino acids and complex compounds than Miller had been able to measure at the time. The new analysis of the vials even identified several important nucleobases—the building blocks of RNA, and perhaps eventually…DNA. “It was an astounding science story,” Edmond concluded, “relegitimizing the notion that perhaps life does simply happen…without divine intervention. It seemed the Miller-Urey experiment had indeed been working, but just needed more time to gestate. Let’s remember one key point: life evolved over billions of years, and these test tubes had been sitting in a closet for just over fifty. If the timeline of this experiment were measured in miles, it was as if our perspective were limited to only the very first inch…” He let that thought hang in the air. “Needless to say,” Edmond went on, “there was a sudden resurgence in interest surrounding the idea of creating life in a lab.” I remember that, Langdon thought. The Harvard biology faculty had thrown

Here’s an example: DNA stores information very nicely, in a durable format that allows for exact duplication. A ribosome turns that stored information into a sequence of amino acids, a protein, which folds up into a variety of chemically active shapes. The combined system, DNA and ribosome, can build all sorts of protein machinery. But what good is DNA, without a ribosome that turns DNA information into proteins? What good is a ribosome, without DNA to tell it which proteins to make? Organisms don’t always leave fossils, and evolutionary biology can’t always figure out the incremental pathway. But in this case we do know how it happened. RNA shares with DNA the property of being able to carry information and replicate itself, although RNA is less durable and copies less accurately. And RNA also shares the ability of proteins to fold up into chemically active shapes, though it’s not as versatile as the amino acid chains of proteins. Almost certainly, RNA is the single A which predates the mutually dependent A* and B. It’s just as important to note that RNA does the combined job of DNA and proteins poorly, as that it does the combined job at all. It’s amazing enough that a single molecule can both store information and manipulate chemistry. For it to do the job well would be a wholly unnecessary miracle. What was the very first replicator ever to exist? It may well have been an RNA strand, because by some strange coincidence, the chemical ingredients of RNA are chemicals that would have arisen naturally on the prebiotic Earth of 4 billion years ago. Please note: evolution does not explain the origin of life; evolutionary biology is not supposed to explain the first replicator, because the first replicator does not come from another replicator. Evolution describes statistical trends in replication. The first replicator wasn’t a statistical trend, it was a pure accident. The notion that evolution should explain the origin of life is a pure strawman—more creationist misrepresentation.

A virus is a small capsule made of membranes and proteins. The capsule contains one or more strands of DNA or RNA, which are long molecules that contain the software program for making a copy of the virus. Some biologists classify viruses as “life forms,” because they are not strictly known to be alive. Viruses are ambiguously alive, neither alive nor dead. They carry on their existence in the borderlands between life and nonlife. Viruses that are outside cells merely sit there; nothing happens. They are dead. They can even form crystals. Virus particles that lie around in blood or mucus may seem dead, but the particles are waiting for something to come along. They have a sticky surface. If a cell comes along and touches the virus and the stickiness of the virus matches the stickiness of the cell, then the virus clings to the cell. The cell feels the virus sticking to it and enfolds the virus and drags it inside. Once the virus enters the cell, it becomes a Trojan horse. It switches on and begins to replicate.

Recall that when genes are active, they make proteins. To manufacture proteins, they use another molecule, RNA, as an intermediary.

It is said that the end of the RNA world hypothesis is near. Perhaps this is an abstraction. Now I Am, as a scientist and biologist, certain that INA is the origin of Life on Earth. The Origin-of-Life study points to INA, not RNA. Why? INA is the origin of DNA and RNA. The INA world hypothesis states that all Life verily is INA. The INA world hypothesis states that biology is undivided and that all variegation is INA perceiving variegation for the purpose not to feel alone, to experience companionship, to Love and Be Loved in return. The INA world hypothesis suggests that INA is the source of all Life on Earth including but not limited to DNA/RNA. The previous RNA theory suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules. DNA, RNA, and proteins are central to life on Earth. DNA stores the instructions for building living things—from bacteria to bumble bees. INA theory is not limited to the Earth but to the Universe for it is all-inclusive. As such INA is not a theory but a scientific law. The kernel of INA-Law is Love. The aforementioned being based on the fact that the meaning of the name DNA is DNA is Deus Non Alligator (its meaning derived from 'Deus non alligator sacramentis' — 'God is not Bound to the sacraments'). RNA was based on the DNA principle. RNA stands for Ram Non Alligator (its meaning derived from 'Rama non alligator sacramentis' — 'Rama is not Bound to the sacraments'). Rama naturally Rama or Ram (Sanskrit: राम, Rāma, also known as Ramachandra, रामचन्द्र, Rāmacandra). As such INA-Law returns to the essence of beingness which is Self (I). The meaning of INA thus being 'I Non Alligator ('I non alligator sacramentis' — 'I is not Bound to the sacraments'). Perhaps the strongest evidence for the INA-Law is Self (I). Self Itself Is. Self Always Is. INA-Law states that Self perceives itself as itself but experiences itself as variegated not to feel alone, to experience Companionship. INA-Law states that Self is pure spirit perceiving itself as matter this although all matter is Self. Furthermore, INA-Law states that division does not exist for there is only Oneself perceiving itself as variegated for Companionship, for Love. Love is as such at the heart of INA-Law. The equation for INA-Law is 'I=Love'.

Stars don’t just shoot out energy and light. When they’re young, they shoot out amino acids and nucleotides— the raw material of DNA, RNA, and proteins. These are carried by the solar wind throughout the solar system. The building blocks of life come from suns. Earth wasn’t just extremely lucky to have these incredibly elegant Legos here. Early in the formation of a solar system, all the planets get showered with them, especially the rocky planets near the sun. Earth isn’t special.

A problem was how nature punctuated the seemingly unbroken DNA and RNA strands. No one could see a biological equivalent for the pauses that separate letters in Morse code, or the spaces that separate words. Perhaps every fourth base was a comma. Or maybe (Crick suggested) commas would be unnecessary if some triplets made “sense” and others made “nonsense.” Then again, maybe a sort of tape reader just needed to start at a certain point and count off the nucleotides three by three. Among the mathematicians drawn to this problem were a group at the new Jet Propulsion Laboratory in Pasadena, California, meant to be working on aerospace research. To them it looked like a classic problem in Shannon coding theory: “the sequence of nucleotides as an infinite message, written without punctuation, from which any finite portion must be decodable into a sequence of amino acids by suitable insertion of commas.” They constructed a dictionary of codes. They considered the problem of misprints

I absolutely can’t stand science, especially biology, which was what we were studying. I couldn’t keep all those terms straight: cell and nucleus, species and phylum and genus, RNA and DNA and who knows what else. You know what is really stupid? The word species. If you have two different kinds of animals or something, then you have two species. But if you have only one kind, then you still have a species. Why not a specie? Or a specy? You don’t have two cats and one cats. Oh, well.

DNA is believed to have emerged through a transformation of RNA, possibly by a virus that converted an RNA gene into a DNA gene. That

Initially compartmentalization might have been accomplished by a nonbiological transitional entity, a protocell, perhaps formed within pores in rocks. (We’ll consider this in more detail below.) But a protocell in a rock pore, even one containing DNA, would not be capable of sustaining complex life. The evolution of true cells depended on some form of compartmentalization outside of such confined spaces. The eventual solution was a lipid casing (membrane) that sequestered RNA, DNA, and the proteins they make, allowing these entities to exist free-floating in the oceans, where they could self-replicate, diversify (that is, evolve), and give rise to all of the organisms that have ever lived.

The plants here aren't like anything on Earth," I tried to explain one night. "They have cells I can't explain. On Earth, all seeds have one or two embryonic leaves, but here they have three or five or eight." "And RNA," Grun said, "not DNA. Nothing has DNA except us.

How does the SIR2 gene actually turn off genes? SIR2 codes for a specialized protein called a histone deacetylase, or HDAC, that enzymatically cleaves the acetyl chemical tags from histones, which, as you’ll recall, causes the DNA to bundle up, preventing it from being transcribed into RNA.

True, viruses are nothing more than a tiny bit of genetic material—a single kind of nucleic acid (segmented or nonsegmented, DNA or RNA) and a coat made of protein molecules. Viruses multiply according to the information contained in this nucleic acid. Everything other than the DNA or RNA is dispensable and serves primarily to ensure that the viral nucleic acid gets to the right place in the right sort of cell in the organism hosting the virus. Viruses
