Assertion :- 28S rRNA in bacteria act as a ribozyme.
Reason:- It is a main component for the formation of phosphodiester bond.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

To analyze the given question, we will break down the assertion and reason step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "28S rRNA in bacteria acts as a ribozyme."
- **Evaluation**: This statement is incorrect because in bacteria, it is the 23S rRNA that functions as a ribozyme, not the 28S rRNA. The 28S rRNA is found in eukaryotes, not in bacteria.

2. **Understanding the Reason**:
- The reason states that "It is the main component for the formation of phosphodiester bond."
- **Evaluation**: This statement is also incorrect in the context of the assertion. While the 23S rRNA does play a role in catalyzing the formation of peptide bonds (not phosphodiester bonds), the assertion incorrectly identifies the rRNA involved.

3. **Conclusion**:
- Since both the assertion and the reason are incorrect, we can conclude that the correct answer is that both the assertion and reason are false.

### Final Answer:
Both assertion and reason are false.
