| Illustration of the US microbiologist Daniel Nathans (1928-1999). Nathans is best known for his application of restriction endonucleases in the mapping of viral genomes. Restriction endonucleases are enzymes that cut DNA (deoxyribonucleic acid) strands at, or near, a specific nucleotide sequence. On hearing of the discovery of these enzymes Nathans started investigating the structure of genes in the simian virus 40 (SV40), a cancer-causing virus. He was able to map the genome and identify the genes responsible for transforming healthy cells into cancerous cells. Nathans received a share of the 1978 Nobel Prize in Physiology or Medicine for his pioneering use of restriction enzymes. | |
