The genomes of _____________________ cannot function as mRNA and therefore these viruses must bring at least one RNA-dependent RNA polymerase into the host cell during entry.

Question

Quizplus · Accepted Answer

Negative-strand RNA viruses have genomes that cannot function as mRNA and therefore require an RNA-dependent RNA polymerase for replication. This polymerase is typically brought into the host cell during entry, either as part of the virus particle or encoded by the viral genome. Positive-strand RNA viruses, on the other hand, have genomes that can serve as mRNA directly, while double-stranded DNA and single-stranded DNA viruses use host polymerases for replication.
