Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially those in the tobacco family. The virus attacks leaf cells and results in characteristic patterns of mottling and discoloration on the leaves. Because it is a retrovirus, which of the following are required to replicate the viral genetic material?

Question

Quizplus · Accepted Answer

Tobacco mosaic virus (TMV) is not a retrovirus; it is a positive-sense single-stranded RNA virus. The question's premise is incorrect. However, for a retrovirus, replication involves transcription, translation, and reverse transcription. Reverse transcription is used to convert RNA into DNA, which is then integrated into the host's genome. This DNA is transcribed to produce viral RNA, which is translated to produce viral proteins.
