Question:
Which of these viruses make use of RNA-dependent DNA polymerase during replication?
Which of these viruses make use of RNA-dependent DNA polymerase during replication?
Show Hint
• Reverse transcriptase → Retroviruses
• Example: HIV
Updated On: May 13, 2026
- HIV
- Dengue virus
- Polio virus
- Hepatitis E virus
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
RNA-dependent DNA polymerase is also known as reverse transcriptase.
• It converts RNA into DNA
• Characteristic of retroviruses
Step 1: Analyzing each virus.
• HIV: Retrovirus → uses reverse transcriptase → Correct.
• Dengue virus: RNA virus, uses RNA-dependent RNA polymerase → Incorrect.
• Polio virus: RNA virus, no reverse transcription → Incorrect.
• Hepatitis E virus: RNA virus, no reverse transcriptase → Incorrect.
Step 2: Selecting the correct answer.
Thus, only HIV uses RNA-dependent DNA polymerase.
• It converts RNA into DNA
• Characteristic of retroviruses
Step 1: Analyzing each virus.
• HIV: Retrovirus → uses reverse transcriptase → Correct.
• Dengue virus: RNA virus, uses RNA-dependent RNA polymerase → Incorrect.
• Polio virus: RNA virus, no reverse transcription → Incorrect.
• Hepatitis E virus: RNA virus, no reverse transcriptase → Incorrect.
Step 2: Selecting the correct answer.
Thus, only HIV uses RNA-dependent DNA polymerase.
