Assertion: Extranuclear DNA occurs in the cytoplasmic matrix.
Reason: It leaks out via nuclear pores into the cytoplasm.

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reasom are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Extranuclear DNA occurs in the cytoplasmic matrix." This refers to DNA that is located outside of the nucleus. In eukaryotic cells, extranuclear DNA is typically found in organelles such as mitochondria and chloroplasts, which are located in the cytoplasm. Therefore, this assertion is true.

2. **Understanding the Reason**: The reason provided is "It leaks out via nuclear pores into the cytoplasm." Nuclear pores are structures that regulate the passage of molecules between the nucleus and the cytoplasm. However, extranuclear DNA does not leak out of the nucleus through these pores. Instead, it is present in the cytoplasm as part of organelles or as plasmids in prokaryotic cells. Thus, this reason is false.

3. **Conclusion**: Since the assertion is true and the reason is false, we can conclude that the correct relationship between the assertion and the reason is that the assertion is true while the reason is false.

4. **Final Answer**: The correct option is that the assertion is true and the reason is false.
