Question

Quizplus · Accepted Answer

Early genes of viruses are transcribed by host RNA polymerase. This is because viruses do not have their own RNA polymerase, and rely on the host machinery to carry out transcription in the initial stages of infection. Later in the viral life cycle, the virus may produce its own polymerase to transcribe its genes. DNA polymerase and rolling circle replication are not directly involved in transcription, but are rather involved in DNA replication.
