Question

Who provided X-ray diffraction data of DNA?

• A. Maurice Wilkins \& Rosalind Franklin
• B. Chargaff
• C. Watson and Crick
• D. Holley

Hint:

Franklin’s Photo 51 was the key evidence that confirmed the helical structure of DNA.

Answer 1

The Correct Option is A

Step 1: Discovery of DNA structure.
The double helical structure of DNA was proposed by Watson and Crick in 1953.
Step 2: X-ray diffraction.
The crucial experimental X-ray diffraction data came from Rosalind Franklin and Maurice Wilkins, which revealed DNA’s helical nature.
Step 3: Conclusion.
Hence, the X-ray diffraction data of DNA was provided by Maurice Wilkins and Rosalind Franklin.
