Is the following statement true? “Antigenic drift and other mutations to the DNA of viruses are always beneficial for the virus.”(1 point)

Responses

No, because different mutations cause a variety of immune responses.

No, because mutated viruses may be less likely to replicate.
No, because mutated viruses may be less likely to replicate.

Yes, because mutated viruses are able to infect more hosts.
Yes, because mutated viruses are able to infect more hosts.

Yes, because mutated viruses have less mRNA so they can copy and replicate faster.

The correct response is:

No, because mutated viruses may be less likely to replicate.

Not all mutations or changes, including those from antigenic drift, are beneficial for the virus. Some mutations can impair the virus's ability to replicate or infect hosts. Therefore, while some mutations can confer advantages (such as evasion of the immune response), others can be detrimental to the virus.
