Number of proteins associated with 60 S ribosome subunit is

Options

A. 46
B. 34
C. 30
D. 21

Answer

To solve the question regarding the number of proteins associated with the 60S ribosome subunit, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ribosome Structure**:
- The ribosome is composed of two subunits: the large subunit (60S) and the small subunit (40S) in eukaryotes. The 60S subunit is the focus of this question.

2. **Identify the Components of the 60S Subunit**:
- The 60S ribosomal subunit is made up of ribosomal RNA (rRNA) and proteins. Specifically, it contains:
- 5S rRNA
- 28S rRNA
- 5.8S rRNA

3. **Know the Number of Proteins**:
- The 60S ribosomal subunit is associated with a specific number of proteins. It is known that the 60S subunit contains **46 proteins**.

4. **Select the Correct Answer**:
- Given the options (46, 34, 30, or 20), the correct answer is **46**.

### Final Answer:
The number of proteins associated with the 60S ribosome subunit is **46**.
