The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.

And so to those of you who may be vitalists I would make this prophecy: what everyone believed yesterday, and you believe today, only cranks will believe tomorrow.

I argued that it was important not to place too much reliance on any single piece of experimental evidence. It might turn out to be misleading, as the 5.1 Å reflection undoubtedly was.

Both of us had decided, quite independently of each other, that the central problem in molecular biology was the chemical structure of the gene.

Before I describe in more detail exactly what is involved in seeing, let me make three general remarks.
