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.

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.

Novel technologies and ideas that impinge on human biology and their perceived impact on human values have renewed strains in the relationship between science and society.
Paul Berg

Today, it is research with human embryonic stem cells and attempts to prepare cloned stem cells for research and medical therapies that are being disavowed as being ethically unacceptable.
Paul Berg

Paradoxically, no such embargo exists for the drugs and therapies that have revolutionized the treatment of serious diseases although many of them were created with the same technologies.
Paul Berg

Yet the effort to inform the public also encouraged responsible public discussion that succeeded in developing a consensus for the measured approach that many scientists supported.
Paul Berg

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.
