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.

In my experience most mathematicians are intellectually lazy and especially dislike reading experimental papers. He seemed to have very strong biological intuitions but unfortunately of negative sign.

Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.

Our ... advantage was that we had evolved unstated but fruitful methods of collaboration ... If either of us suggested a new idea, the other, while taking it seriously, would attempt to demolish it in a candid but non-hostile manner.

One can say, looking at the papers in this symposium, that the elucidation of the genetic code is indeed a great achievement. It is, in a sense, the key to molecular biology because it shows how the great polymer languages, the nucleic acid language and the protein language, are linked together.

Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.

Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.
