Question

Which scientists produced X-ray diffraction images that revealed the helical structure of DNA during 1951–52?

Options

• Watson and Crick

• Rosalind Franklin and Maurice Wilkins

• Griffith and Avery

• Hershey and Chase

Answer 1

Rosalind Franklin and Maurice Wilkins produced X-ray diffraction images between 1951 and 1952 that provided critical evidence for the helical structure of DNA. These images were instrumental in Watson and Crick's formulation of the double helix model in 1953.
