Which of the following processes within viral replication is the greatest source of genetic variation in RNA virus populations?
A) High mutation rate due to lack of proofreading of RNA genome replication errors.
B) Transcription from the host cell RNA polymerase introduces numerous mutations.
C) Capsid proteins from the host cell can replace the viral capsid.
D) Viral RNA is translated by host cell ribosomes.

Question

Quizplus · Accepted Answer

RNA viruses lack proofreading mechanisms during genome replication, leading to a high mutation rate and significant genetic variation within the virus population. This is not the case for transcription, capsid protein replacement, or translation.
