Answer

To find the total number of amino acids in the capsid of the Tobacco Mosaic Virus (TMV) with 2130 capsomeres, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of TMV**:
- TMV (Tobacco Mosaic Virus) has a capsid that is made up of units called capsomeres.

2. **Identify the Number of Capsomeres**:
- According to the problem, TMV has 2130 capsomeres.

3. **Determine the Number of Amino Acids per Capsomere**:
- Each capsomere is composed of approximately 158 amino acids.

4. **Calculate the Total Number of Amino Acids**:
- To find the total number of amino acids in the capsid, multiply the number of capsomeres by the number of amino acids per capsomere:
\[ \text{Total Amino Acids} = \text{Number of Capsomeres} \times \text{Amino Acids per Capsomere} \]
\[ \text{Total Amino Acids} = 2130 \times 158 \]

5. **Perform the Calculation**:
- Calculate \( 2130 \times 158 \):
\[ 2130 \times 158 = 336540 \]

6. **Select the Correct Option**:
- The total number of amino acids in the capsid of TMV is 336540. Therefore, the correct answer is (a) 336540.

### Final Answer:
(a) 336540
