Assertion: DNA molecule acts as a template for synthesis of both RNA and DNA.
Reason: DNA duplex has the feature of right handed coiling and antiparallel.

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

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "DNA molecule acts as a template for synthesis of both RNA and DNA."
- This is true because during the processes of transcription and replication, DNA serves as a template. In transcription, a segment of DNA is used to synthesize RNA, and in replication, DNA is used to create a new DNA strand.

2. **Understanding the Reason**:
- The reason states that "DNA duplex has the feature of right-handed coiling and antiparallel."
- This is also true. The structure of DNA is a double helix that coils in a right-handed manner, and the two strands of the DNA are oriented in opposite directions (antiparallel).

3. **Evaluating the Relationship**:
- While both the assertion and reason are true, we need to determine if the reason correctly explains the assertion.
- The assertion discusses the role of DNA as a template for synthesis, while the reason describes the structural characteristics of DNA. The structural features (right-handed coiling and antiparallel strands) do not directly explain why DNA can act as a template for synthesis.

4. **Conclusion**:
- Therefore, the conclusion is that both the assertion and reason are true, but the reason does not provide a correct explanation for the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
