SAN DIEGO - Nobel Prize-winning scientist Francis Crick, who with James Watson discovered the spiral, "double-helix" structure of DNA, paving the way for everything from DNA blood tests to genetically engineered tomatoes, has died. He was 88.
It was 1953, while working in Cavendish Laboratory in Cambridge, England, that the British-born Crick, 36 at the time, and the American-born Watson, just 24, struck upon the famous double-helix structure ? like a twisted ladder ? of deoxyribonucleic acid, or DNA.
A half-century later, the biotechnology industry is based largely upon Crick's and Watson's discovery. So, too, are genetically engineered foods like bigger tomatoes and innovative medical technologies like gene therapy.
