The 80S ribosome has two sub units which are

Options

A. A) 30S and 50S
B. B) 40S and 60S
C. C) 40S and 40S
D. D) 20S and 60S

Answer

To answer the question about the two subunits of the 80S ribosome, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ribosomes**:
- Ribosomes are cellular structures responsible for protein synthesis. They are composed of ribosomal RNA (rRNA) and proteins.

2. **Identifying the Types of Ribosomes**:
- Ribosomes are classified based on their sedimentation rates, which are measured in Svedberg units (S). The two main types of ribosomes are prokaryotic ribosomes (70S) and eukaryotic ribosomes (80S).

3. **Analyzing the 80S Ribosome**:
- The 80S ribosome, which is found in eukaryotic cells, consists of two subunits: a larger subunit and a smaller subunit.

4. **Determining the Subunits of the 80S Ribosome**:
- The larger subunit of the 80S ribosome is 60S, and the smaller subunit is 40S.

5. **Conclusion**:
- Therefore, the two subunits of the 80S ribosome are 60S and 40S.

### Final Answer:
The two subunits of the 80S ribosome are 60S and 40S.
