Looking back, I realize that nurturing curiosity and the instinct to seek solutions are perhaps the most important contributions education can make.

Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has substantially disappeared as the science revealed that such exchanges occur in nature.

Fears of creating new kinds of plagues or of altering human evolution or of irreversibly altering the environment were only some of the concerns that were rampant.

But I felt it necessary to be part of the war effort and I enlisted in the Navy to be a flyer.

Looking back, I realize that nurturing curiosity and the instinct to seek solutions are perhaps the most important contributions education can make.

By then, I was making the slow transition from classical biochemistry to molecular biology and becoming increasingly preoccupied with how genes act and how proteins are made.

That work led to the emergence of the recombinant DNA technology thereby providing a major tool for analyzing mammalian gene structure and function and formed the basis for me receiving the 1980 Nobel Prize in Chemistry.
