Most RNA viruses carry which of the following enzymes?
Dominik [7]

Answer:

The correct answer will be option-B.

Explanation:

Viral polymerases are the enzymes which play an important role in the viral genome transcription and replication.

Retrovirus is the single-stranded RNA viruses which replicate through a DNA intermediate and therefore requires the <em>RNA-dependent DNA polymerase or reverse transcriptase</em>. Reverse transcriptase encodes DNA from the strand of RNA which can be replicated and helps in the reproduction of the virus.

Thus, option- B is the correct answer.
