The correct Answer is:
To solve the question "Retrovirus employs ….. To make complementary DNA from RNA," we need to identify the correct enzyme used by retroviruses to synthesize complementary DNA (cDNA) from their RNA genome. ### Step-by-Step Solution: 1. **Understanding Retroviruses**: Retroviruses are a type of RNA virus that have RNA as their genetic material. They are known for their ability to convert their RNA into DNA. 2. **Identifying the Process**: The process by which retroviruses convert RNA into DNA is known as reverse transcription. This is a crucial step in the life cycle of retroviruses. 3. **Enzyme Involved**: The enzyme that catalyzes the conversion of RNA to complementary DNA (cDNA) is called reverse transcriptase. This enzyme synthesizes cDNA from the viral RNA genome. 4. **Evaluating Options**: - **DNA Polymerase**: This enzyme is involved in DNA replication but does not synthesize DNA from RNA. Thus, it is not the correct answer. - **Restriction Endonuclease**: This enzyme cuts DNA at specific sequences but does not play a role in synthesizing cDNA from RNA. Therefore, it is also incorrect. - **Reverse Polymerase**: This term is incorrect; the correct term is reverse transcriptase. Hence, this option is not valid. - **Reverse Transcriptase**: This is the correct enzyme that retroviruses use to synthesize cDNA from RNA. 5. **Conclusion**: The correct answer to the question is **reverse transcriptase**. ### Final Answer: Retrovirus employs **reverse transcriptase** to make complementary DNA from RNA.
