What is the main reason why DNA viruses tend to be more genetically stable than RNA viruses?
- RNA viruses have error correction mechanisms
- DNA repair mechanisms exist in the host cell (correct)
- DNA viruses replicate more slowly
- RNA viruses are more precisely adapted for transmission and replication
