Richard J. Roberts

Richard J. Roberts is a British biochemist best known for his discovery of "restriction enzymes," proteins that cut DNA at specific sequences. This finding has been fundamental to genetic research, allowing scientists to manipulate DNA and advance fields like biotechnology and genetics. His work has enabled advancements in cloning, gene therapy, and the development of genetically modified organisms. Roberts received the Nobel Prize in Physiology or Medicine in 1993 for his contributions, which have significantly enhanced our understanding of genes and their functions. His discoveries continue to impact medicine, agriculture, and biological research today.
