Werner ArberBorn 3 Jun 1929.Swiss microbiologist corecipient (with Americans Daniel Nathans and Hamilton Othanel Smith) of the 1978 Nobel Prize for Physiology or Medicine. All three were cited for their work in molecular genetics, specifically the discovery and application of restriction enzymes that break the giant molecules of deoxyribonucleic acid (DNA) into manageable pieces, small enough to be separated for individual study but large enough to retain bits of the genetic information inherent in the sequence of units that make up the original substance. |
