Another problem for those studying viral origins and evolution is their high rate of mutation, particularly the case in RNA retroviruses like:
a) HIV
b) Bacteriophages
c) Pox viruses
d) HAV
Answer:
The answer is (a) HIV.
Explanation:
RNA retroviruses like HIV have a high rate of mutation, which makes it difficult to study their origins and evolution. This is because RNA viruses lack the proofreading mechanisms that are present in DNA viruses, which can result in errors during replication. As a result, RNA viruses like HIV can mutate rapidly and frequently, leading to the emergence of new strains that may be resistant to existing treatments.

Answer:
please mark me as a brainlist
Explanation:
Correct! The answer is (a) HIV. RNA retroviruses, like HIV, indeed have a high mutation rate due to their lack of proofreading mechanisms during replication. This rapid mutation can lead to the emergence of new viral variants and poses challenges for studying their origins and evolution
