Question

Genetic material of TMV is

• A. RNA
• B. DNA
• C. DNA and RNA
• D. None of the above

Answer 1

The correct option is A RNA

TMV has RNA as a genetic material. The RNA present in the TMV is a positive-sense single-stranded RNA virus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discolouration on the leaves. TMV was the first virus ever to be discovered.

So, the correct answer is option A.
