What was Rosalind Franklin’s role in the discovery of the structure of DNA?
|
|
She discovered that DNA is made of nucleotides
|
|
|
She carried out X-ray diffraction experiments leading to the determination that DNA is a double helix.
|
|
|
She carried out X-ray diffraction experiments and concluded that DNA strands run in opposite directions.
|
|
|
She produced the three-dimensional molecular model of DNA to show that it is a double helix.

Explanation:
Detailed explanation-1: -The discovery of the structure of DNA in 1953 was made possible by Dr Rosalind Franklin’s X-ray diffraction work at King’s. Her creation of the famous Photo 51 demonstrated the double-helix structure of deoxyribonucleic acid: the molecule containing the genetic instructions for the development of all living organisms.
