John Sulston (British biologist)

John Sulston was a British biologist known for his pioneering work in genetics and developmental biology. He played a key role in mapping the complete genome of the roundworm *Caenorhabditis elegans*, which became a model organism for studying gene function. His research greatly advanced our understanding of how genes control development and behavior. Sulston was also a prominent advocate for ethical considerations in science and was awarded the Nobel Prize in Physiology or Medicine in 2002 for his contributions to the field, highlighting the importance of genetic research in understanding life’s fundamental processes.
