Which is present in the larger subunit of eukaryotic ribosome

Options

A. 28 S RNA
B. 5.8 S RNA
C. 5 S RNA
D. All the above.

Answer

To answer the question "Which is present in the larger subunit of the eukaryotic ribosome?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Eukaryotic Ribosomes**:
- Eukaryotic ribosomes are composed of two subunits: a larger subunit and a smaller subunit.

2. **Identify the Components of the Smaller Subunit**:
- The smaller subunit of the eukaryotic ribosome contains 18S ribosomal RNA (rRNA).

3. **Identify the Components of the Larger Subunit**:
- The larger subunit contains three types of rRNA: 28S, 5.8S, and 5S.

4. **Differentiate Between Eukaryotic and Prokaryotic Ribosomes**:
- In eukaryotic cells, the larger subunit is typically referred to as the 60S subunit, which includes the aforementioned rRNA species.

5. **Conclusion**:
- Therefore, the components present in the larger subunit of the eukaryotic ribosome are 28S, 5.8S, and 5S rRNA.

### Final Answer:
The larger subunit of the eukaryotic ribosome contains 28S, 5.8S, and 5S rRNA.
