Cell And Molecular Biology Quotes

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up altogether of one hundred thousand million atoms, far more complicated than any machine built by man and absolutely without parallel in the nonliving world.

When I started reading the literature of molecular biology, I was stunned by certain descriptions. Admittedly, I was on the lookout for anything unusual, as my investigation had led me to consider that DNA and its cellular machinery truly were an extremely sophisticated technology of cosmic origin. But as I pored over thousands of pages of biological texts, I discovered a world of science fiction that seemed to confirm my hypothesis. Proteins and enzymes were described as 'miniature robots,' ribosomes were 'molecular computers,' cells were 'factories,' DNA itself was a 'text,' a 'program,' a 'language,' or 'data.' One only had to do a literal reading of contemporary biology to reach shattering conclusions; yet most authors display a total lack of astonishment and seem to consider that life is merely 'a normal physiochemical phenomenon.

Look at any randomly selected piece of your world. Encoded deep in the biology of every cell in every blade of grass, in every insect’s wing, in every bacterium cell, is the history of the third planet from the Sun in a Solar System making its way lethargically around a galaxy called the Milky Way. Its shape, form, function, colour, smell, taste, molecular structure, arrangement of atoms, sequence of bases, and possibilities for the future are all absolutely unique. There is nowhere else in the observable Universe where you will see precisely that little clump of emergent, living complexity. It is wonderful.

To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity.

If it's true there's a beginning to the universe, as modern cosmologists now agree, then this implies a cause that transcends the universe. If the laws of physics are fine-tuned to permit life, as contemporary physicists are discovering, then perhaps there's a designer who fine-tuned them. If there's information in the cell, as molecular biology shows, then this suggests intelligent design. To get life going in the first place would have required biological information; the implications point beyond the material realm to a prior intelligent cause. -Stephen C Meyer, PHD

Suddenly I realized that a cell's life is controlled by the physical and energetic environment and not by its genes. Genes are simply molecular blueprints used in the construction of cells, tissues, and organs. The environment serves as a "contractor" who reads and engages those genetic blueprints and is ultimately responsible for the character of a cell's life. It is a single cell's "awareness" of the environment, not its genes, that sets into motion the mechanisms of life.

The living cell is the most complex system of its size known to mankind. Its host of specialized molecules, many found nowhere else but within living material, are themselves already enormously complex. They execute a dance of exquisite fidelity, orchestrated with breathtaking precision. Vastly more elaborate than the most complicated ballet, the dance of life encompasses countless molecular performers in synergetic coordination. Yet this is a dance with no sign of a choreographer. No intelligent supervisor, no mystic force, no conscious controlling agency swings the molecules into place at the right time, chooses the appropriate players, closes the links, uncouples the partners, moves them on. The dance of life is spontaneous, self-sustaining, and self-creating.

Biology is run by intricate cellular mechanisms. Cellular mechanisms are run by Nature. Thus, the more we attempt to understand Nature, the more we get closer to our existential properties.

Nanotechnology will enable the design of nanobots: robots designed at the molecular level, measured in microns (millionths of a meter), such as “respirocytes” (mechanical red-blood cells).33 Nanobots will have myriad roles within the human body, including reversing human aging (to the extent that this task will not already have been completed through biotechnology, such as genetic engineering).

Proto-oncogenes and tumor suppressors are the molecular pivots of the cell. They are the gatekeepers of cell division, and the division of cells is so central to our physiology that genes and pathways that coordinate this process intersect with nearly every other aspect of our biology. In the laboratory, we call this the six-degrees-of-separation-from-cancer rule: you can ask any biological question, no matter how seemingly distant—what makes the heart fail, or why

The unification of our understanding of life with our understanding of matter and energy was the greatest scientific achievement of the second half of the twentieth century. One of its many consequences was to pull the rug out from under social scientists like Kroeber and Lowie who had invoked the “sound scientific method” of placing the living and nonliving in parallel universes. We now know that cells did not always come from other cells and that the emergence of life did not create a second world where before there was just one. Cells evolved from simpler replicating molecules, a nonliving part of the physical world, and may be understood as collections of molecular machinery—fantastically complicated machinery, of course, but machinery nonetheless. This leaves one wall standing in the landscape of knowledge, the one that twentieth-century social scientists guarded so jealously. It divides matter from mind, the material from the spiritual, the physical from the mental, biology from culture, nature from society, and the sciences from the social sciences, humanities, and arts. The division was built into each of the doctrines of the official theory: the blank slate given by biology versus the contents inscribed by experience and culture, the nobility of the savage in the state of nature versus the corruption of social institutions, the machine following inescapable laws versus the ghost that is free to choose and to improve the human condition. But this wall, too, is falling.

James Tour is a leading origin-of-life researcher with over 630 research publications and over 120 patents. He was inducted into the National Academy of Inventors in 2015, listed in “The World’s Most Influential Scientific Minds” by Thomson Reuters in 2014, and named “Scientist of the Year” by R&D Magazine. Here is how he recently described the state of the field: We have no idea how the molecules that compose living systems could have been devised such that they would work in concert to fulfill biology’s functions. We have no idea how the basic set of molecules, carbohydrates, nucleic acids, lipids and proteins were made and how they could have coupled in proper sequences, and then transformed into the ordered assemblies until there was the construction of a complex biological system, and eventually to that first cell. Nobody has any idea on how this was done when using our commonly understood mechanisms of chemical science. Those that say that they understand are generally wholly uninformed regarding chemical synthesis. Those that say, “Oh this is well worked out,” they know nothing—nothing—about chemical synthesis—nothing. … From a synthetic chemical perspective, neither I nor any of my colleagues can fathom a prebiotic molecular route to construction of a complex system. We cannot even figure out the prebiotic routes to the basic building blocks of life: carbohydrates, nucleic acids, lipids, and proteins. Chemists are collectively bewildered. Hence I say that no chemist understands prebiotic synthesis of the requisite building blocks, let alone assembly into a complex system. That’s how clueless we are. I have asked all of my colleagues—National Academy members, Nobel Prize winners—I sit with them in offices. Nobody understands this. So if your professors say it’s all worked out, if your teachers say it’s all worked out, they don’t know what they’re talking about.23

This, in turn, has given us a “unified theory of aging” that brings the various strands of research into a single, coherent tapestry. Scientists now know what aging is. It is the accumulation of errors at the genetic and cellular level. These errors can build up in various ways. For example, metabolism creates free radicals and oxidation, which damage the delicate molecular machinery of our cells, causing them to age; errors can build up in the form of “junk” molecular debris accumulating inside and outside the cells. The buildup of these genetic errors is a by-product of the second law of thermodynamics: total entropy (that is, chaos) always increases. This is why rusting, rotting, decaying, etc., are universal features of life. The second law is inescapable. Everything, from the flowers in the field to our bodies and even the universe itself, is doomed to wither and die. But there is a small but important loophole in the second law that states total entropy always increases. This means that you can actually reduce entropy in one place and reverse aging, as long as you increase entropy somewhere else. So it’s possible to get younger, at the expense of wreaking havoc elsewhere. (This was alluded to in Oscar Wilde’s famous novel The Picture of Dorian Gray. Mr. Gray was mysteriously eternally young. But his secret was the painting of himself that aged horribly. So the total amount of aging still increased.) The principle of entropy can also be seen by looking behind a refrigerator. Inside the refrigerator, entropy decreases as the temperature drops. But to lower the entropy, you have to have a motor, which increases the heat generated behind the refrigerator, increasing the entropy outside the machine. That is why refrigerators are always hot in the back. As Nobel laureate Richard Feynman once said, “There is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at all inevitable and that it is only a matter of time before biologists discover what it is that is causing us the trouble and that this terrible universal disease or temporariness of the human’s body will be cured.

What if a chemical, either found in nature or cooked up in a lab, could tap into the motivational circuit and drive dopamine neurons artificially from within the brain? Intriguingly, this may be exactly how drugs of abuse work. Although different drugs of abuse have distinct molecular targets and very different behavioral effects, they all drive the electrical activity of dopamine neurons or the release of dopamine from these cells (while nonaddictive brain-targeted drugs like Prozac do not).5

The rediscovery of Mendel's laws of heredity in the opening weeks of the 20th century sparked a scientific quest to understand the nature and content of genetic information that has propelled biology for the last hundred years. The scientific progress made [since that time] falls naturally into four main phases, corresponding roughly to the four quarters of the century." "The first established the cellular basis of heredity: the chromosomes. The second defined the molecular basis of heredity: the DNA double helix. The third unlocked the informational basis of heredity [i.e. the genetic code], with the discovery of the biological mechanism by which cells read the information contained in genes, and with the invention of the recombinant DNA technologies of cloning and sequencing by which scientists can do the same." The sequence of the human genome, the project asserted, marked the starting point of the "fourth phase" of genetics. This was the era of "genomics" - the assessment of the entire genomes of organisms, including humans. There is an old conundrum in philosophy that asks if an intelligent machine can ever decipher its own instruction manual. For humans, the manual was now complete. Deciphering it, reading it, and understanding it would be quite another matter.

The rest of the organism was as natural as any other ordinary cell. Indeed, Venter’s synthetic genome depended on the rest of the recipient cell’s natural and native apparatus for its expression: it depended on the cell’s molecular machinery of transcription, translation, and replication, its ribosomes, metabolic pathways, its energy supplies, and so on.

Although molecular biology was not born in 1953 with the discovery of the structure of DNA by Watson and Crick, its elucidation has provided the molecular biologist with tools and techniques that have propelled the science forward. All the information required to make a human being is contained in a single cell. The molecules comprising this fertilized egg will organize the development, sustain the life, allow for the reproduction of, and ultimately execute the demise of an individual. Molecular biology is the study of the way in which molecules function to organize life. Remarkably, the same molecules and principles lie at the heart of all the life sciences, as they control the fundamental machinery of cells. The field of molecular biology concerns macromolecules such as nucleic acids, proteins, carbohydrates, and fats, and their interrelationships, that are essential for life itself.

Mission is purpose magnified, Purpose is potential focused, Potential is protoplasm evolving, Protoplasm is a pocket universe.

The scientific basis for separating neocortical from limbic brain matter rests on solid neuroanatomical, cellular, and empirical grounds. As viewed through the microscope, limbic areas exhibit a far more primitive cellular organization than their neocortical counterparts. Certain radiographic dyes selectively stain limbic structures, thus painting the molecular dissimilarity between the two brains in clean, vivid strokes. One researcher made an antibody that binds to cells of the hippocampus—a limbic component—and found that those same fluorescent markers stuck to all parts of the limbic brain, lighting it up like a biological Christmas tree, without coloring the neocortex at all. Large doses of some medications destroy limbic tissue while leaving the neocortex unscathed, a sharp-shooting feat enabled by evolutionary divergence in the chemical composition of limbic and neocortical cell membranes.

When chemists artificially produce an amino acid or a sugar they almost always synthesize only a single product at a time, which they manage by carefully controlling the experimental conditions for the selected reaction, such as temperature and the concentrations of the various ingredients, to optimize the synthesis of their target compound. This is not an easy task and requires careful control of many different conditions inside customized flasks, condensers, separation columns, filtration devices and other elaborate chemical apparatus. Yet every living cell in your body is continually synthesizing thousands of distinct biochemicals within a reaction chamber filled with just a few millionths of a microliter of fluid.*7 How do all those diverse reactions proceed concurrently? And how is all this molecular action orchestrated within a microscopic cell? These questions are the focus of the new science of systems biology; but it is fair to say that the answers remain mysterious!

Vaccines are little pieces of bacteria or viruses injected into the body to give the immune system an education. They work by ramping up your own defensive system so that you're ready to fight the bacteria or virus upon first contact, without becoming sick first.

Flawed scientific studies reported a possible link between the MMR vaccine and autism. This information, combined with confusion about vaccines, has made some parents afraid to get their kids vaccinated. This fear persists despite five extensive scientific studies that failed to find a link between the MMR vaccine and autism. Most people don't remember the dangers of measles, so the fear of autism looms larger than their fear of measles. In a way, vaccines are a victim of their own success — they prevent disease, so people lose their fear of the disease and stop vaccinating.

The dream of every cell is to become two cells’ said François Jacob, the most lyrical revolutionary of molecular biology. No cell lives the dream so wholly or so senselessly as a cancer cell, turning dream to nightmare. Nothing else captures the myopic immediacy of natural selection so starkly. The moment is all that matters for selection: there is no foresight, no balance, no slowing at the prospect of doom. Just the best ploy for the moment, for me, right now, not for the many, and often mistaken. Cancer cells die in piles, necrotic flesh worse than the trenches. The decimated survivors mutate, evolve, adapt, exploit their shifting environment, selfish to the bitter end. Their horror is that they know no bounds. They will eat away at our flesh to fuel their pointless lives and deaths, until, if we are unlucky, they take us too. I am writing about cancer, but must confess that I have the pointless greed and destruction of humanity at the back of my mind. May we find it within ourselves to be better than cancer cells.

Not long after his first meeting with Watson and Crick, Chargaff elected himself polemicist on behalf of all that has been left out—for the early discoverers, Friedrich Miescher and Oswald Avery; for the role of protein in the chromosome; for complexity and crowding in the cell; for humility and caution in the laboratory. “I am against the over-explanation of science, because I think it impedes the flow of scientific imagination and associations,” he said. “My main objection to molecular biology is that by its claim to be able to explain everything it actually hinders the free flow of scientific ideas. But there is not a scientist I have met who would share my opinion.

The models that characterize the robustness of neuronal networks bear little resemblance to the molecular biology models used to explain brain cell function, which in turn differ from the psychological models used to explain cognitive biases.

P2 - We are well on the way in a number of areas. Both billionaires and big Pharma are getting increasingly interested and money is starting to pour into research because it is clear we can see the light at the end of the tunnel which to investors equates to return on investment. Numerous factors will drive things forward and interest and awareness is increasing rapidly among both scientists, researchers and the general population as well as wealthy philanthropists. The greatest driving force of all is that the baby boomers are aging and this will place increasing demands on healthcare systems. Keep in mind that the average person costs more in medical expenditure in the last year of their life than all the other years put together. Also, the number of workers is declining in most developed countries which means that we need to keep the existing population working and productive as long as possible. Below are a list which are basically all technologies potentially leading to radical life extension with number 5 highlighted which I assume might well be possible in the second half of the century: 1. Biotechnology - e.g stem cell therapies, enhanced autophagy, pharmaceuticals, immunotherapies, etc 2. Nanotechnology - Methods of repairing the body at a cellular and molecular level such as nanobots. 3. Robotics - This could lead to the replacement of increasing numbers of body parts and tends to go hand in hand with AI and whole brain emulation. It can be argued that this is not life extension and that it is a path toward becoming a Cyborg but I don’t share that view because even today we don’t view a quadriplegic as less human if he has four bionic limbs and this will hold true as our technology progresses. 4. Gene Therapies - These could be classified under the first category but I prefer to look at it separately as it could impact the function of the body in very dramatic ways which would suppress genes that negatively impact us and enhance genes which increase our tendency toward longer and healthier lives. 5. Whole brain emulation and mindscaping - This is in effect mind transfer to a non biological host although it could equally apply to uploading the brain to a new biological brain created via tissue engineering this has the drawback that if the original brain continues to exist the second brain would have a separate existence in other words whilst you are identical at the time of upload increasing divergence over time will be inevitable but it means the consciousness could never die provided it is appropriately backed up. So what is the chance of success with any of these? My answer is that in order for us to fail to achieve radical life extension by the middle of the century requires that all of the above technologies must also fail to progress which simply won't happen and considering the current rate of development which is accelerating exponentially and then factoring in that only one or two of the above are needed to achieve life extension (although the end results would differ greatly) frankly I can’t see how we can fail to make enough progress within 10-20 years to add at least 20 to 30 years to current life expectancy from which point progress will rapidly accelerate due to increased funding turning aging at the very least into a manageable albeit a chronic incurable condition until the turn of the 22nd century. We must also factor in that there is also a possibility that we could find a faster route if a few more technologies like CRISPR were to be developed. Were that to happen things could move forward very rapidly. In the short term I'm confident that we will achieve significant positive results within a year or two in research on mice and that the knowledge acquired will then be transferred to humans within around a decade. According to ADG, a dystopian version of the post-aging world like in the film 'In Time' not plausible in the real world: "If you CAREFULLY watch just the first

A key point in Dr. Lipton’s astute explanation of biological activity is that at any one time, cells—like the entire human organism—can be either in defensive mode or growth mode but not both. Our perceptions of the environment are stored in cellular memory. When early environmental influences are chronically stressful, the developing nervous system and the other organs of the PNI super-system repeatedly receive the electric, hormonal and chemical message that the world is unsafe or even hostile. Those perceptions are programmed in our cells on the molecular level. Early experiences condition the body’s stance toward the world and determine the person’s unconscious beliefs about herself in relationship to the world. Dr. Lipton calls that process the biology of belief. Fortunately, human experience and the ever-unfolding potential of human beings ensure that the biology of belief, though deeply physiologically ingrained, is not irreversible.

bacteria are cells, and viruses are not — which makes a big difference when it comes to medicine. Antibiotics target bacterial cells, and they don't work on viruses!

Proteins are constructed by the combined efforts of two processes, called transcription and translation

We are invited by Dawkins and Darwin to believe that the evolution of the eye proceeded step-by-step through a series of plausible intermediates in infinitesimal increments. But are they infinitesimal? Remember that the "light-sensitive spot" that Dawkins takes as his atarting point requires a cascade of factors, including 11-cis-retinal and rhodopsin, to function. Dawkins doesn't mention them. And where did the "little cup" come from? A ball of cells--from which the cup must be made--will tend to be rounded unless held in the correct shape by molecular supports. In fact, there are dozens of complex proteins involved in mantaining cell shape, and dozens more that control extracellular structure; in their absence, cells take the shape of so many soap bubbles. Do these structures represent single-step mutations? Dawkins did not tell us how the apparently simple "cup" shape came to be. And although he reassures us that any "translucent material" would be an improvement (recall that Haeckel mistakenly thought it would be easy to produce cells since they were certainly just "simple lumps"), we are not told how difficult it is to produce a "simple lens". In short, Dawkins's explanation is only addressed to the level of what is called gross anatomy.

The ‘epi’ in epigenetics is derived from Greek and means at, on, to, upon, over or beside. The DNA in our cells is not some pure, unadulterated molecule. Small chemical groups can be added at specific regions of DNA. Our DNA is also smothered in special proteins. These proteins can themselves be covered with additional small chemicals. None of these molecular amendments changes the underlying genetic code. But adding these chemical groups to the DNA, or to the associated proteins, or removing them, changes the expression of nearby genes. These changes in gene expression alter the functions of cells, and the very nature of the cells themselves. Sometimes, if these patterns of chemical modifications are put on or taken off at a critical period in development, the pattern can be set for the rest of our lives,

Robert A. Freitas Jr.—a pioneering nanotechnology theorist and leading proponent of nanomedicine (reconfiguring our biological systems through engineering on a molecular scale), and author of a book with that title150—has designed robotic replacements for human blood cells that perform hundreds or thousands of times more effectively than their biological counterparts. With Freitas’s respirocytes (robotic red blood cells) a runner could do an Olympic sprint for fifteen minutes without taking a breath.

had never really thought about this last until I took a graduate level course in developmental biology, which forever changed my appreciation of the miracle of birth. In this course I learned what’s known about how a fertilized egg becomes a human baby at the molecular level. The more I learned about it, the more impossible it seemed. How does an organism convert food into the raw materials necessary to make more of itself? How could something as complex as a human being—as a human mind—be built up from a single magic cell? The answer, of course, is that it can’t be. Can. Not. Be. Of all the impossible things I can imagine, this is the most impossible of all. Trillions of cells, specializing and working in concert, all arising from a single cell. More than a hundred billion neurons all spawned from this same humble beginning, all in the right configuration to produce consciousness. It was utterly absurd.

Focusing on information flow will help us to understand better how cells and organisms work ... We need to describe the molecular interactions and biochemical transformations that take place in living organisms, and then translate these descriptions into the logical circuits that reveal how information is managed ... Two phases of work are required for such a programme: to describe and catalogue the logic circuits that manage information in cells, and to simplify analysis of cellular biochemistry so that it can be linked to the logical circuits ... A useful analogy is an electronic circuit. Representations of such circuits use symbols to define the nature and function of the electronic components used. They also describe the logic relationships between the components, making it clear how information flows through the circuit. A similar conceptualization is required of the logic modules that make up the circuits that manage information in cells.

working cells of your body are constantly reading the DNA code and using the instructions to build molecules, such as proteins, that they need to do

Life relies on digitally coded instructions, translating between sequence and structure (from nucleotides to proteins), with ribosomes reading, duplicating, and interpreting the sequences on the tape. But any resemblance ends with the different method of addressing by which the instructions are carried out. In a digital computer, the instructions are in the form of COMMAND (ADDRESS) where the address is an exact (either absolute or relative) memory location, a process that translates informally into “DO THIS with what you find HERE and go THERE with the result.” Everything depends not only on precise instructions, but also on HERE, THERE, and WHEN being exactly defined. In biology, the instructions say, “DO THIS with the next copy of THAT which comes along.” THAT is identified not by a numerical address defining a physical location, but by a molecular template that identifies a larger, complex molecule by some smaller, identifiable part. This is the reason that organisms are composed of microscopic (or near-microscopic) cells, since only by keeping all the components in close physical proximity will a stochastic, template-based addressing scheme work fast enough. There is no central address authority and no central clock. Many things can happen at once. This ability to take general, organized advantage of local, haphazard processes is the ability that (so far) has distinguished information processing in living organisms from information processing by digital computers.

Science of Life, Class in Session (Sonnet 2087-2088) Nature doesn't kill anybody, nor does it save anybody - life and death are human constructs, just like beauty and the grotesque - nature is above all that, not in an almighty, all-knowing sort of way, but more of an indifferent sort of way - because in nature, nothing's born, nothing dies, they just change shape, and some of those shapes are sentient, some intelligent, some neither - and each identity gets restructured as they go through the shape-shifting, which includes restructure of sentience, or non-sentience, as the case may be. Same elements that make the nonsentient stars, when they change shape into organic material, such as humans, they produce sentience, but as a human corpse decay into nature, those elements get absorbed into the soil, into trees, bugs, and all sorts of creatures, thus they seep into a diverse range of sentient and nonsentient materials - and thus the cycle continues, from the birth of the universe till the end of the universe - beyond that, I don't know - nobody does - it doesn't matter what happens after, what matters is, how you behave now.
