Daniel Nathans

Daniel Nathans was an American microbiologist known for his groundbreaking work in molecular biology. He played a key role in developing techniques to clone and manipulate DNA, which transformed genetics and biotechnology. In 1978, he was awarded the Nobel Prize in Physiology or Medicine for his contributions to the discovery of restriction enzymes—molecules that cut DNA at specific sequences. This discovery has had profound implications, enabling advances in genetic research, medicine, and biotechnology. Nathans' work laid the foundation for techniques used in genetic engineering, including the development of recombinant DNA technology, which is essential in producing insulin and other therapies.
