In the early 1950s, the identity of genetic material was still a matter of debate. The discovery of the helical structure of double-stranded DNA settled the matter — and changed biology forever.

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to ...

Watson and Crick describe structure of DNA 1953 Photo: Model of DNA molecule. In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were ...

Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.

On February 28, 1953, James Watson and Francis Crick informally announced that they had discovered the double-helical structure of DNA. They soon reported their find more formally. On April 25 ...
