Question

Explain how the discoveries by Rosalind Franklin helped Watson and Crick build an accurate model of DNA.

Answer 1

In 1952, Rosalind Franklin produced an image of DNA that suggested it contained two strands twisted in a double helix with a phosphate backbone and bases inside.

Franklin calculated the diameter of DNA, the distance between strands and bases, the angle of the helix, and the number of bases per coil.

Watson and Crick used this information to build and accurate model of DNA.

Answer 2

Rosalind Franklin was the one who pioneered the structure of DNA through his X-ray diffraction images at King's College. His failure to explain the double helix structure was the reason why Watson and Crick were the person who were accounted by the discovery. The huge model by Cirick and Watson proved the theory of Franklin who failed to give an evidence.
