Amino Quotes

It is one of the more striking generalizations of biochemistry - which surprisingly is hardly ever mentioned in the biochemical textbooks - that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature. (Francis Crick)

It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid.

Francis Crick

A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement.

Francis Crick

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 meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority.

Francis Crick

There's a new science out called orthomolecular medicine. You correct the chemical imbalance with amino acids and vitamins and minerals that are naturally in the body.

Margot Kidder

The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.

Francis Crick

This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.

Francis Crick

Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid.

Francis Crick

A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.

Francis Crick

[The smallest bacterium] is so much more like people than Stanley Miller's mixtures of chemicals, because it already has these system properties. So to go from a bacterium to people is less of a step than to go from a mixture of amino acids to that bacterium. (Lynn Margulis)

If one compares the sequence of amino acids that go to form the protein haemoglobin, it becomes apparent that humans and chimps are identical and do not differ in a single site.

Simon Conway Morris

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

Michael Behe

Looked at from the perspective of twentieth-century earth, we see three great stages in the dynamic process of the universe. To this whole process, as it spreads out over perhaps ten billion years of time and ten billion light years of space, we give the name evolution, and we see three great patterns within it. The first is physical evolution. This presumably started with the development of the most elementary particles (whatever they may be); then of neutrons, protons, electrons, and radiations; then of elements from hydrogen to uranium and beyond formed by combining protons and electrons; then of chemical compounds; then finally of increasingly complex molecules from amino acids, and proteins to the great watershed of DNA, the beginnings of life.

Kenneth Boulding

That the primary effect of gene mutation may be as simple as the substitution of a single amino acid by another and may lead to profound secondary changes in protein structure and properties has recently been strongly indicated by the work of Ingram on hemoglobin.

Edward Lawrie Tatum

Part of my daily regime is my glucosamine and, of course, a multitude of multivitamins. Branched-chain amino acids, glutamine, of course protein. I have one protein shake a day, and that is immediately after my training.

Dwayne Johnson

We know that if memory is destroyed in one part of the brain, it can be sometimes re-created on a different part of the brain. And once we can unravel that amino chain of chemicals that is responsible for memory, I see no reason why we can't unlock it and, essentially, wipe out what's there.

J. Michael Straczynski

Cori Bargmann... has studied two variants of C. elegans... The only difference between the two is one amino acid in an otherwise shared receptor protein. Transferring the receptor from a social worm to a solitary worm makes the solitary worm social.

Eric Kandel

A machine, a mechanism, no more than a tool - technological brother to the hoe, the wrench, the hammer - and yet as far a cry from these as the human brain was from that first amino acid which had come into being on this planet when the Earth was very young. One was tempted, Enoch thought, to say that this was as far as a tool could go, that it was the ultimate in the ingenuity possessed by any brain. But that would be a dangerous way of thinking, for perhaps there was no limit, there might, quite likely, be no such condition as the ultimate; there might be no time when any creature or any group of creatures could stop at any certain point and say, this is as far as we can go, there is no use of trying to go farther. For each new development produced, as side effects, so many other possibilities, so many other roads to travel, that with each step one took down any given road there were more paths to follow. There'd never be an end, he thought - no end to anything.
