Nucleotides Quotes

Some planets evolved genetic structures roughly similar to Earth's, incorporating some if not all the nucleotides involved in terrestrial genetics (perhaps not coincidentally, the intelligent species of these planets have been known to consume humans from time to time; ~ John Scalzi

Of all the things we could have said to the people of other planets, we chose to fire into space a capsule containing the model for the double helix structure, the composition of DNA and the formation of nucleotides. Not a message that declared: it is sunny here it also rains a lot we love colours and dope we sign and we dance we cook up a storm with anything we can find we are fucked up in too many ways but we are a funny bunch so may we request the pleasure of your company ~ Meena Kandasamy

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

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

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. ~ James Gleick

The variety of polyprenol phosphate sugars may turn out to be as large as that of sugar nucleotides. ~ Luis Federico Leloir

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. ~ Frederick Sanger
