Question

Which enzyme is required for RNA viruses to replicate their genomes?
A)reverse transcriptase
B)RNA replicase
C)DNA polymerase
D)host RNA polymerase

Accepted Answer

RNA replicase is required for RNA viruses to replicate their genomes. This enzyme can replicate RNA without a template, allowing the virus to produce multiple copies of its genome in the cytoplasm of infected cells. Reverse transcriptase is required for retroviruses (such as HIV) to convert their RNA genome into DNA before it can be integrated into the host genome, while DNA polymerase is involved in DNA replication. Host RNA polymerase is not directly involved in the replication of RNA virus genomes.
