Which viral lineages tend to predominate in a population due to their ability to rapidly adapt and evade host immune responses?
A
DNA viruses
B
Bacteriophages
C
RNA viruses
D
Retroviruses
Verified step by step guidance1
Understand the characteristics of different types of viruses. DNA viruses have a stable genetic material, which means they mutate less frequently compared to RNA viruses.
Recognize that RNA viruses have a higher mutation rate due to the lack of proofreading mechanisms during replication. This allows them to rapidly adapt to changing environments and evade host immune responses.
Consider the role of retroviruses, which are a subset of RNA viruses. They use reverse transcription to integrate their genetic material into the host genome, which can also contribute to their adaptability.
Bacteriophages are viruses that infect bacteria, and while they can evolve, they are not typically involved in evading host immune responses in the same way as RNA viruses in multicellular organisms.
Conclude that RNA viruses tend to predominate in populations due to their ability to rapidly mutate and adapt, making them more capable of evading host immune responses compared to DNA viruses and bacteriophages.
