The single-stranded RNA of positive-sense RNA viruses can act directly as mRNA for translation in the cytoplasm of the host cell.

Question

Quizplus · Accepted Answer

Positive-sense RNA viruses have RNA genomes that can directly serve as mRNA for translation in the host cell cytoplasm. In contrast, negative-sense RNA viruses require RNA-dependent RNA polymerase to synthesize a complementary positive-sense RNA strand before translation can occur.
