Question

Quizplus · Accepted Answer

Negative-sense single-stranded RNA viruses have only a few genes, including one that allows them to make mRNA from their genome. They cannot regenerate themselves by reverse transcription and do not have distinct lipids in their plasma membranes. Some plant viruses are negative-sense single-stranded RNA viruses, but they are not all referred to as mosaic viruses. The size of their genomes can vary, but many have a size of a few thousand to tens of thousands of base pairs.
