The capsid of tobacco mosaiv virus (TMV) has capsomeres numbering

Options

A. 3120
B. 2130
C. 1230
D. 231

Answer

To determine the number of capsomeres in the capsid of the Tobacco Mosaic Virus (TMV), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of TMV**:
- TMV is a virus that has a cylindrical or helical shape. It consists of a protein coat known as a capsid, which surrounds its genetic material.

2. **Identify the Genetic Material**:
- TMV contains single-stranded RNA as its genetic material, which is approximately 6400 bases long.

3. **Define Capsomeres**:
- Capsomeres are the individual protein subunits that make up the capsid of a virus. They play a crucial role in forming the protective coat around the viral RNA.

4. **Find the Number of Capsomeres**:
- For TMV, it is known that the capsid is composed of 2130 capsomeres.

5. **Select the Correct Option**:
- Given the options provided, the correct number of capsomeres in the TMV capsid is 2130.

### Final Answer:
The capsid of the Tobacco Mosaic Virus (TMV) has 2130 capsomeres.
