Genetic material of TMV is

Options

A. ds RNA
B. ssRNA
C. ssDNA
D. Proteinaceous

Answer

### Step-by-Step Solution:

1. **Identify the Virus**: The question asks about the genetic material of TMV, which stands for Tobacco Mosaic Virus.

2. **Understand the Nature of TMV**: TMV is a plant virus that primarily infects tobacco plants and other members of the Solanaceae family.

3. **Determine the Genetic Material**: The genetic material of TMV is a type of nucleic acid. Specifically, it is important to note that TMV contains RNA as its genetic material.

4. **Specify the Type of RNA**: TMV has a positive-sense single-stranded RNA genome. This means that its RNA is not double-stranded and is single-stranded.

5. **Review the Options**: The options provided in the question are:
- A) Double-stranded RNA
- B) Single-stranded RNA
- C) Single-stranded DNA
- D) Proteinaceous

6. **Select the Correct Answer**: Based on the information gathered, the correct answer is B) Single-stranded RNA.

### Final Answer:
The genetic material of TMV is **single-stranded RNA**.
