Subunits Of Nucleic Acids Quotes

the sample volume the protein concentration and viscosity of the sample the degree of purity of the protein product the presence of nucleic acids, pyrogens, and proteolytic enzymes in the sample the ease with which different types of adsorbents can be washed free from adsorbed contaminants and denatured protein. ~ Jan-Christer Janson

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). ~ Richard J. Roberts

So while Pauling struggled with his model, Watson and Crick turned theirs inside out, so the negative phosphorus ions wouldn't touch. This gave them a sort of twisted ladder - the famed double helix. ~ Sam Kean

It is, I believe, justifiable to make the generalization that anything an organic chemist can synthesize can be made without him. All he does is increase the probability that given reactions will 'go.' So it is quite reasonable to assume that given sufficient time and proper conditions, nucleotides, amino acids, proteins, and nucleic acids will arise by reactions that, though less probable, are as inevitable as those by which the organic chemist fulfills his predictions. So why not self-duplicating virus-like systems capable of further evolution? ~ George Wells Beadle

The nucleic acids, as constituents of living organisms, are comparable In importance to proteins. There is evidence that they are Involved In the processes of cell division and growth, that they participate In the transmission of hereditary characters, and that they are important constituents of viruses. An understanding of the molecular structure of the nucleic acids should be of value In the effort to understand the fundamental phenomena of life. ~ Linus Pauling

It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule. ~ Francis Crick

The tar is an extremely rich collection of complex organic molecules, including the constituent parts of proteins and nucleic acids. The stuff of life, it turns out, can be very easily made. ~ Carl Sagan

It's the pattern that matters, you see. Not the choice of building materials. Life is information, shaped by natural selection. Carbon's just fashion, nucleic acids mere optional accessories. Electrons can do all that stuff, if they're coded the right way. It's all just pattern. ~ Peter Watts

If the results of the present study on the chemical nature of the transforming principle are confirmed, then nucleic acids must be regarded as possessing biological specificity the chemical basis of which is as yet undetermined. ~ Oswald Theodore Avery

People of a "scientific" bent have been known to ridicule those, like Harry, who believe unlikely notions such as the idea that the Universe was created in six days and that the first human being was formed by God breathing into a lump of clay. It should be noted that the latest scientific theories entail that (1) all of the matter in the Universe was once compressed into an area smaller than the point of a pin; and (2) life came about when a chance collision of molecules accidentally lined up three million nucleic acids in exactly the right order to form a self-replicating protein. ~ Robert Kroese

We are now witnessing, after the slow fermentation of fifty years, a concentration of technical power aimed at the essential determinants of heredity, development and disease. This concentration is made possible by the common function of nucleic acids as the molecular midwife of all reproductive particles. Indeed it is the nucleic acids which, in spite of their chemical obscurity, are giving to biology a unity which has so far been lacking, a chemical unity. ~ C.D. Darlington

The results serve to disprove the tetranucleotide hypothesis. It is, however, noteworthy-whether this is more than accidental, cannot yet be said-that in all desoxypentose nucleic acids examined thus far the molar ratios of total purines to total pyrimidines, and also of adenine to thymine and of guanine to cytosine, were not far from 1. ~ Erwin Chargaff

Chance alone is at the source of every innovaton, of all creation in the biosphere. Pure chance, only chance, absolute but blind liberty is at the root of the prodigious edifice that is evolution ... It today is the sole conceivable hypothesis, the only one that squares with observed and tested fact. Stating life began by the chance collision of particles of nucleic acid in the "prebiotic soup." ~ Jacques Monod

In living organisms, nucleic acid molecules are the only indefinite hereditary replicators, or at least they were until the invention of language and music. ~ John Maynard Smith

The success in the determination of the high-resolution structures of ribosomal subunits and eventually the whole ribosome was the culmination of decades of effort. ~ Venkatraman Ramakrishnan

The discovery of an interaction among the four hemes made it obvious that they must be touching, but in science what is obvious is not necessarily true. When the structure of hemoglobin was finally solved, the hemes were found to lie in isolated pockets on the surface of the subunits. Without contact between them how could one of them sense whether the others had combined with oxygen? And how could as heterogeneous a collection of chemical agents as protons, chloride ions, carbon dioxide, and diphosphoglycerate influence the oxygen equilibrium curve in a similar way? It did not seem plausible that any of them could bind directly to the hemes or that all of them could bind at any other common site, although there again it turned out we were wrong. To add to the mystery, none of these agents affected the oxygen equilibrium of myoglobin or of isolated subunits of hemoglobin. We now know that all the cooperative effects disappear if the hemoglobin molecule is merely split in half, but this vital clue was missed. Like Agatha Christie, Nature kept it to the last to make the story more exciting. There are two ways out of an impasse in science: to experiment or to think. By temperament, perhaps, I experimented, whereas Jacques Monod thought. ~ Max F. Perutz

How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons. ~ Francis Crick

In this atmosphere I soon became interested in nucleic acids. ~ Frederick Sanger

I feel now, as we did then, that for an effective approach to the problem of nucleic acid biosynthesis, it was essential to understand the biosynthesis of the simple nucleotides and the coenzymes and to have these concepts and methodology well in hand. ~ Arthur Kornberg

Virus particles contain single molecules of nucleic acid. ~ Alfred Hershey

We are, in a way, temporary ambulatory repositories for our nucleic acids. This does not deny our humanity; it does not prevent us from pursuing the good, the true and the beautiful. But it would be a great mistake to ignore where we have come from in our attempt to determine where we are going. ~ Carl Sagan

The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids. ~ Michael Behe

Numerous studies have clearly demonstrated that coconut oil has a neutral effect on cholesterol levels. The reason coconut oil does not adversely affect cholesterol is because it is composed primarily of medium-chain fatty acids (MCFA). These fatty acids are different from those commonly found in other food sources and are burned almost immediately for energy production, and so they are not converted into body fat or cholesterol to the degree other fats are and do not affect blood cholesterol levels. ~ Bruce Fife

Vices and frailties correct each other, like acids and alkalies. If each vicious man had but one vice, I do not know how the world could go on. ~ Richard Whately

Many a modern preacher is far less concerned with preaching Christ and Him crucified than he is with his popularity with his congregation. A want of intellectual backbone makes him straddle the ox of truth and the ass of nonsense. Bending the knee to the mob rather than God would probably make them scruple at ever playing the role of John the Baptist before a modern Herod. The acids of modernity are eating away the fossils of orthodoxy. ~ Fulton J. Sheen

When you are taking fixed dosages of amino acids, what is happening in the kidneys mimics exactly what is happening in the brain. ~ Daniel Kalish

Valkyrie stood there and waited for her to start making sense.
"There is a vegetable-plant hybrid we've been working on, modifying the genes and receptors, mutating the proteins and acids so that they are, in effect, neurotransmitters. Our work on the synapses alone has been quite illuminating."
Valkyrie stood there and waited for her to start making sense. ~ Derek Landy

It is one of the striking generalizations of biochemistry - which surprisingly is hardly ever mentioned in the biochemical text-books - that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature. As far as I am aware the presently accepted set of twenty amino acids was first drawn up by Watson and myself in the summer of 1953 in response to a letter of Gamow's. ~ Francis Crick

The transition of food to being an industrial product really has been a fundamental problem," Willett said. "First, the actual processing has stripped away the nutritional value of the food. Most of the grains have been converted to starches. We have sugar in concentrated form, and many of the fats have been concentrated and then, worst of all, hydrogenated, which creates trans-fatty acids with very adverse effects on health. ~ Michael Moss

If you have a universe that was just the mirror image of the one we know about, then in fact, presumably it would have right-handed amino acids. That's why I'm only half kidding when I say there is a guy on the other side of the universe with his heart on the right hand side. ~ Ronald Breslow
