Question

Who amongst the following scientists had no contribution in the development of the double helix model for the structure of DNA?

• A. Maurice Wilkins
• B. Rosalind Franklin
• C. Erwin Chargaff
• D. Meselson and Stahl

Answer 1

Answer: (D)

Rosalind Franklin along with Maurice Wilkins produced the X-ray diffraction data of DNA and Erwin Chargaff proposed through careful experimentation two rules that helped lead to the discovery of the double helix structure of DNA called the Chargaff rules. Meselson and Stahl did not have any contribution in the development of double helix but were involved in the experimentation of the semi-conservative nature of replication of DNA

So, the correct answer is 'Meselson and Stahl'.
