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:
NEET 2023 (All India)
Options:
Answer:
B
Solution:
RNA contains
- A ribose sugar
- A phosphate group
- Purines (like A and G) and pyrimidines (like C and U).
Being unstable, which is due to the hydroxyl group present at the 2'-carbon of the ribose, RNA mutates faster than DNA. That is also the reason that viruses having RNA genome and shorter life span mutate and evolve faster.
