Given below are two statements.
Statement I - RNA acts as biocatalyst and catalytic RNA is ribozyme.
Statement II - Due to repeated replication and mutation, varieties of RNA molecules of varying sizes are formed.
In the light of above statements, select the correct option given below:

Options

  1. ABoth statement I and statement II are correct.
  2. BBoth statement I and statement II are incorrect.
  3. CStatement I is correct but statement II is incorrect.
  4. DStatement I is incorrect but statement II is correct.

Correct answer

A. Both statement I and statement II are correct.

Step-by-step solution

Statement I is correct. RNA can act as a biocatalyst in certain biochemical reactions, and these catalytic RNA molecules are known as ribozymes.

Statement II is also correct. According to the RNA world hypothesis, early RNA molecules underwent repeated replication. During this process, mutations occurred, which led to the formation of a diverse variety of RNA molecules of varying sizes and functions, eventually driving early evolution.

Therefore, both Statement I and Statement II are correct.

Answer: Both statement I and statement II are correct.
