The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
The DNA structure was officially discovered around 1953 by James Watson and Francis Crick, with the help of Rosalind Franklin's research on X-ray diffraction patterns of DNA. Their model of the double helix structure of DNA was published in the journal Nature in April 1953.
James Watson and Francis Crick are credited with first identifying the structure of DNA in 1953. Their model of the DNA double helix revolutionized the field of molecular biology.
KEY FACT In 1953, James Watson and Francis Crick put forward their hypothesis that DNA had a double helix structure. Their first attempt to identify the structure of DNA was not successful, however, in 1953 they put forward their hypothesis that DNA had a double helix structure.

The tool used to show the structure of DNA was X-ray crystallography. This technique was used by Rosalind Franklin and Maurice Wilkins to capture the first image of the double helix structure of DNA.
