Given below are two statements Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.

Question

Given below are two statements:

Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.

Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence. In the light of the above statements, choose the most appropriate answer from the options given below:

1. A. Both statement I and statement II are correct
2. B. Both statement I and statement II are incorrect
3. C. Statement I is correct but statement II is incorrect
4. D. Statement I is incorrect but statement II is correct (Correct answer)

Correct Answer

Option D — Statement I is incorrect but statement II is correct

Detailed Solution & Explanation

The correct answer is Statement I is incorrect but statement II is correct.

Key Points

• Both tRNA and rRNA interact with mRNA during translation (tRNA reads codons, rRNA of the ribosome binds mRNA) — so Statement I is incorrect.
• RNA interference (RNAi) does occur in all eukaryotes as a method of cellular defence (against viruses/transposons) — Statement II is correct.
