Given below are two statements:

Statement I: RNA mutates at a faster rate.

Statement II: Viruses having RNA genome and shorter life span mutate and evolve faster.

In the light of the above statements, choose the correct answer from the options given below:

1. Statement I false but Statement II is true.

2. Both Statement I and Statement II are true.

3. Both Statement I and Statement II are false.

4. Statement I is true but Statement II is false.

Best answer

Answer: 2. Both Statement I and Statement II are true.

Key idea: RNA genomes mutate faster than DNA genomes.

  • Statement I is true: RNA is less stable and has less proofreading, so it mutates at a faster rate.
  • Statement II is true: RNA viruses with short life spans mutate and evolve faster.

Option 2.
