Given below are two statements: Statement I: The 2'-OH group present at every nucleotide in RNA is a reactive group that makes RNA labile and easily degradable. Statement II: RNA is known to be catalytic in nature, which makes it chemically less reactive and structurally more stable than DNA. In the light of the above statements, choose the correct answer from the options given below:

Options

  1. ABoth Statement I and Statement II are true.
  2. BBoth Statement I and Statement II are false.
  3. CStatement I is true but Statement II is false.
  4. DStatement I is false but Statement II is true.

Correct answer

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

Step-by-step solution

Statement I is true because the 2' -OH group present at every nucleotide in RNA is a reactive group that makes RNA labile and easily degradable. Statement II is false because RNA is known to be catalytic in nature, which makes it chemically more reactive and structurally less stable than DNA. DNA is chemically less reactive and structurally more stable compared to RNA. Answer: Statement I is true but Statement II is false.
