In the following questions a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion (A): Teminism is bidirectional flow of information.
Reason (R): It requires DNA dependent RNA polymerase enzyme.

A

Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

B

Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

C

Assertion (A) is true but reason (R) is false.

D

Assertion (A) is false but reason (R) is true.

The correct Answer is:
### Step-by-Step Solution 1. **Understanding the Assertion (A)**: The assertion states that "Teminism is a bidirectional flow of information." - **Explanation**: Teminism refers to the process of reverse transcription, where RNA is used as a template to synthesize DNA. This process indeed represents a bidirectional flow of information because it involves the conversion of RNA back into DNA, in addition to the traditional flow of information from DNA to RNA during transcription. 2. **Understanding the Reason (R)**: The reason states that "It requires DNA dependent RNA polymerase enzyme." - **Explanation**: The statement is incorrect because reverse transcription is catalyzed by the enzyme reverse transcriptase, not DNA-dependent RNA polymerase. DNA-dependent RNA polymerase is involved in the transcription process (DNA to RNA), but it does not play a role in reverse transcription. 3. **Evaluating the Statements**: - The assertion (A) is correct because Teminism does represent a bidirectional flow of information. - The reason (R) is incorrect because it incorrectly identifies the enzyme involved in reverse transcription. 4. **Conclusion**: Based on the evaluation, the correct choice is that the assertion is correct, but the reason is wrong. ### Final Answer **C**: The assertion is correct, but the reason is wrong.
