TMV (Tobacco Mosaic Virus) has

Options

A. (a) dsDNA + Protein
B. (b) ssRNA + Protein
C. (c) ssDNA + Protein
D. (d) dsRNA + Protein

Answer

To answer the question regarding the genome material of the Tobacco Mosaic Virus (TMV), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding TMV**: TMV stands for Tobacco Mosaic Virus, which is a well-known virus that infects tobacco and other plants. It is important to know that TMV is one of the first viruses to be discovered and studied.

2. **Identifying the Genome Type**: The question specifically asks about the type of genetic material that TMV possesses. Viruses can have different types of genetic material, including DNA or RNA, and can be either single-stranded or double-stranded.

3. **Researching TMV's Genetic Material**: TMV is known to have RNA as its genetic material. More specifically, it has single-stranded RNA (ssRNA). This is a crucial detail as it distinguishes TMV from other viruses that may have double-stranded RNA or DNA.

4. **Size of the Genome**: The size of TMV's genome is approximately 6 kilobases (Kb). This information helps confirm the identity of the virus and its classification.

5. **Conclusion**: Based on the information gathered, TMV has a single-stranded RNA (ssRNA) genome. The correct answer to the question is that TMV has ssRNA plus protein.

### Final Answer:
TMV (Tobacco Mosaic Virus) has single-stranded RNA (ssRNA) as its genome material.
