Acid Quote by Francis Crick

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…

Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one…

— Francis Crick

Attempts have been made from a study of the changes produced by mutation to obtain the relative order of the bases within various triplets,…

— 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…

— 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…

— 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…

— 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…

— 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…

— Francis Crick

It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed…

— Francis Crick

It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less…

— Francis Crick

“The genetic code is a product of biology and is messy, illogical and inelegant. It is highly redundant, but to bewilderingly varied degrees: one…

— Matthew Cobb

That the primary effect of gene mutation may be as simple as the substitution of a single amino acid by another and may lead…
