Given below are two statements :

Statement I : In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.

Statement II : DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repairing mechanism.

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

1. Both statement I and statement II are correct

2. Both statement I and statement II are incorrect

3. Statement I is correct but statement II is incorrect

4. Statement I is incorrect but statement II is correct

1 answer

Best answer

Answer: 1. Both statement I and statement II are correct

Key idea: Both statements describe the RNA world idea correctly.

Statement I: RNA was the first genetic material and also acts as a catalyst (ribozyme). Being reactive, it is unstable. This is correct.

Statement II: DNA evolved from RNA. Its complementary double strands and repair mechanisms make it more stable. This is correct.

So both are correct.
