Question

Genetic nature of Ribonucleic acid was discovered by:

• A. Boveri
• B. Hugo de Vries
• C. Frankel Conrat
• D. Khorana

Hint:

RNA as genetic material was first confirmed by Frankel Conrat using TMV experiments.

Answer 1

The Correct Option is C

Step 1: Understanding RNA as Genetic Material Frankel Conrat demonstrated that RNA, rather than protein, carries genetic information in viruses. He conducted experiments on Tobacco Mosaic Virus (TMV) by separating its protein and RNA components and reconstituting the virus, proving that RNA was the genetic material. 

Step 2: Identifying the Correct Answer - Option (1) Boveri (Incorrect – Known for chromosomal inheritance). 
- Option (2) Hugo de Vries (Incorrect – Proposed mutation theory).
- Option (3) Frankel Conrat (Correct – Discovered RNA as genetic material). 
- Option (4) Khorana (Incorrect – Known for genetic code deciphering).
