C) Archaea
D) DNA viruses

Question

Quizplus · Accepted Answer

RNA viruses are known for their high mutation rates that can lead to the emergence of new strains or variants, making it difficult to develop effective vaccines or treatments. This is why RNA viruses such as influenza, HIV, and SARS-CoV-2 are major epidemiological problems. Gram-positive bacteria and archaea have lower mutation rates compared to RNA viruses, and DNA viruses, while they can also mutate, are generally less unpredictable in their genetic changes.
