Question

Quizplus · Accepted Answer

Retroviruses are RNA viruses that contain the enzyme reverse transcriptase, which allows them to convert their RNA genome into DNA. This DNA can then integrate into the host cell's genome, where it can be transcribed and translated into viral proteins. Therefore, option B, which refers to the presence of reverse transcriptase, is the correct choice.
