Acid 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

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

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

— Edward Lawrie Tatum

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

Finally one should add that in spite of the great complexity of protein synthesis and in spite of the considerable technical difficulties in synthesizing…

— Francis Crick

“Part of the problem was that no one knew exactly how a cell took a nucleic acid sequence and turned it into a blob…

— Matthew Cobb

“He believed that the mutations were manifestations of the ancient past he had written about—evidence of a genetic code that was not completely eradicated.”

— E.B. Hudspeth

The fundamental biological variant is DNA. That is why Mendel's definition of the gene as the unvarying bearer of hereditary traits, its chemical identification…

— Jacques Monod

“This chapter reveals and elaborates upon the exquisite beauty of protein structure.”

— Reginald H. Garrett

“Right. Mutation is the trigger that moves evolution forward. So, how do mutations happen?”

— Koji Suzuki

“The bradys must hold that, on the average, cumulative selection has to add a little information to the genome at each step. But of…
