Molecular biology is essentially the practice of biochemistry without a license.

If at one time or another I have brushed a few colleagues the wrong way, I must apologize: I had not realized that they were covered with fur.

The results serve to disprove the tetranucleotide hypothesis. It is, however, noteworthy-whether this is more than accidental, cannot yet be said-that in all desoxypentose nucleic acids examined thus far the molar ratios of total purines to total pyrimidines, and also of adenine to thymine and of guanine to cytosine, were not far from 1.

There are no such men today. We have created a mechanism that makes it practically impossible for a real genius to appear. In my own field the biochemist Fritz Lipmann or the much maligned Linus Pauling were very talented people. But generally, geniuses everywhere seem to have died out by 1914. Today, most are mediocrities blown up by the winds of the time.

Scientific fashions last longer than women's fashions but not as long as men's

Science is now the craft of the manipulation, substitution and deflection of the forces of nature. What I see coming is a gigantic slaughterhouse, an Auschwitz, in which valuable enzymes, hormones, and so on will be extracted instead of gold teeth.

Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'
