Question

The genetic nature of TMV (Tobacco Mosaic Virus) as RNA was confirmed by:

• A. Stanley
• B. Beijerinck
• C. Frankel Conrot
• D. Iwanowski

Hint:

This finding was crucial for virology, proving that RNA can be genetic material and capable of causing infection independently of DNA.

Answer 1

The Correct Option is C

To solve the problem, we need to identify the scientist who confirmed that the genetic nature of TMV (Tobacco Mosaic Virus) is RNA.

1. Understanding the TMV and RNA Discovery:
The discovery that the genetic material of the Tobacco Mosaic Virus (TMV) is RNA was confirmed through experiments conducted by various scientists. In particular, the work of Frankel-Conrat provided definitive evidence that the RNA is responsible for the viral properties of TMV.

2. Analyzing the Options:
Stanley: Although Stanley made important contributions to the study of TMV, the confirmation that TMV's genetic material is RNA is attributed to Frankel-Conrat.
Beijerinck: Beijerinck is known for his work on viruses, but he did not confirm that the genetic material of TMV is RNA.
Frankel-Conrat: Frankel-Conrat is the correct scientist who confirmed that TMV's genetic material is RNA, through experiments involving the isolation and characterization of the virus.
Iwanowski: Iwanowski is known for his discovery of the concept of viruses but did not specifically confirm that TMV's genetic material is RNA.

3. Conclusion:
Based on the historical contributions to the understanding of TMV and RNA.

Final Answer:
The correct option is (C) Frankel-Conrat.
