B) is unique to oncogenic RNA viruses.
C) is involved in transcription.
D) synthesizes DNA.

Question

Quizplus · Accepted Answer

DNA-dependent RNA polymerase is involved in the process of transcription, which is the synthesis of RNA from a DNA template. It is not involved in synthesizing DNA. It also typically functions as a multi-subunit enzyme rather than a single polypeptide subunit. While some viruses do encode their own RNA polymerase, they are not necessarily oncogenic and this enzyme is present in all organisms that use DNA as genetic material.
