| biography:
| Molecular biologist, born in New York City, USA. He graduated from Johns Hopkins Medical School, where he carried out genetic research (from 1967) and became professor of microbiology (1973). In the 1970s he obtained enzymes from bacteria which would split genes to give genetically active fragments; these ‘restriction enzymes’ allowed the possibility of genetic engineering of a new kind, as well as providing a tool for DNA sequencing. He shared the 1978 Nobel Prize for Physiology or Medicine with Werner Arber and Daniel Nathans. |
