Which enzyme is responsible for the replication of RNA viral genomes without a DNA intermediate?
A. Reverse transcriptase
B. RNA-dependent RNA polymerase✓ Correct Answer
C. DNA polymerase III
D. Taq polymerase
💡 Solution & Explanation
RNA-dependent RNA polymerase is an essential enzyme utilized by RNA viruses to catalyze the replication of their RNA strands without requiring a DNA intermediate. Reverse transcriptase is used by retroviruses like HIV to transcribe single-stranded RNA into double-stranded DNA. Understanding viral replication enzymes helps explain the mechanisms of action of various antiviral drugs.
