Q. Consider the following statements:
1.The Mpox virus is capable of spreading through human-to-human transmission.
2.Viruses evolve by making changes to their genetic material through
3.RNA viruses mutate less frequently than DNA viruses.
How many of the statements given above are correct?
Answer: B
Notes:
Explanations –
Statements 1 and 2 are correct. The mpox virus (formerly known as monkeypox) can spread through human-to-human transmission, particularly through close contact. Viruses evolve by introducing mutations in their genetic material (DNA or RNA), which can lead to changes in their behavior, adaptability, and virulence.
Statement 3 is incorrect. RNA viruses mutate at a much higher rate than DNA viruses because RNA polymerases lack proofreading mechanisms, making them more prone to errors during replication.
