Bases Quote by 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…

— 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…

— 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…

— 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

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 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 has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.

— Francis Crick

How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show…

— Francis Crick

If you know the mother's genome and the father's genome, and you see that the children have some genes that neither parent has, then…

— Leroy Hood

It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a…
