Question

Quizplus · Accepted Answer

RNA retroviruses regenerate themselves by reverse transcription, which means they convert their RNA genome into DNA and then integrate it into the host genome. This is a unique characteristic of retroviruses. Choices A, B, D, and E are incorrect because they either do not accurately describe retroviruses or do not relate to their defining characteristic of reverse transcription.
