For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

Exactly 66 years ago, on April 25, 1953, Francis Crick and James Watson published their famous article that showed that the shape of DNA is a double helix. They weren’t able to see DNA directly - it’s ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97. The ...

On April 21, thousands of scientists gathered in South San Francisco, Calif. to form the world's largest DNA helix. Organized by Genentech, Inc., a biotechnology company that produces research in ...

Researchers have identified a new way to measure DNA torsional stiffness -- how much resistance the helix offers when twisted -- information that can potentially shed light on how cells work. Cornell ...

Many people picture the classic double-stranded helix when picturing a molecule of DNA, but DNA is also capable of forming far more complex structures. Usually though, those structures are not ...

James D. Watson, the brilliant but controversial American biologist whose 1953 discovery of the structure of DNA, the molecule of heredity, ushered in the age of genetics and provided the foundation ...
