The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...

Rosalind Franklin made a crucial contribution to the discovery of the double ... ray diffraction picture of a DNA molecule was Watson's inspiration (the pattern was clearly a helix).
