Which statement is true regarding the replication mechanisms of RNA viruses? A) All RNA viruses replicate their genomes in the nucleus. B) RNA viruses are immune to mutations during replication. C) RNA viruses frequently encode their own polymerases for replication. D) RNA viruses exclusively use DNA-dependent RNA polymerases.
Understand the Problem
The question is asking which statement accurately describes the replication mechanisms of RNA viruses, specifically looking for the true statement among the options provided.
Answer
RNA viruses frequently encode their own polymerases for replication.
RNA viruses frequently encode their own polymerases for replication.
Answer for screen readers
RNA viruses frequently encode their own polymerases for replication.
More Information
RNA viruses often encode RNA-dependent RNA polymerases to replicate their genomes, allowing them to produce RNA from RNA, which is essential for their replication cycles.
Tips
A common mistake is to assume all RNA viruses replicate in the nucleus or use DNA-dependent RNA polymerases, which is not correct.
