James D. Watson, whose co-discovery of the twisted ladder structure of DNA in 1953 helped ignite a revolution in medicine, crime fighting, genealogy and ethics, has died.
He was 97 years old.
The breakthrough, made when the Chicago-born Watson was just 24, made him a hallowed figure in the scientific world for decades. But toward the end of his life, he faced condemnation and professional criticism for offensive remarks, including saying that black people were less intelligent than white people.
Watson shared the Nobel Prize in 1962 with Francis Crick and Maurice Wilkins for the discovery that deoxyribonucleic acid, or DNA, is a double helix, made up of two strands that wrap around each other to create what resembles a long, gently twisting ladder.
This realization was a major breakthrough. It immediately suggested how hereditary information is stored and how cells duplicate their DNA when they divide.
Replication begins with the two strands of DNA separating as a chain.
