Drawing on your knowledge of evolution, why is treatment and/or vaccination against viruses particularly difficult?
A) Their high replication rate increases the probability of beneficial mutations.
B) Their high mutation rate increases the probability of beneficial mutations.
C) Viral reassortment increases the pathogenicity of viruses.
D) Their high replication rate increases the probability of beneficial mutations and their high mutation rate increases the probability of beneficial mutations.
E) Their high replication rate increases the probability of beneficial mutations, their high mutation rate increases the probability of beneficial mutations, and viral reassortment increases the pathogenicity of viruses.

Question

Quizplus · Accepted Answer

Viruses have high replication rates and high mutation rates, both of which increase the likelihood of mutations that could be beneficial to the virus, such as those conferring resistance to treatments or vaccines. Additionally, viral reassortment, which can occur when two different viruses infect the same cell and exchange genetic material, can lead to new virus strains with increased pathogenicity, making treatment and vaccination efforts more challenging.
