NEET 2025, Biology Q70: Transcription and Translation

NEET2025Biology
Q.

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, chocse the most appropriate answer from the options given below :

  1. A

    Statement I is incorrect but statement II is correct

  2. B

    Both statement I and statement II are correct

  3. C

    Both statement I and statement II are incorrect

  4. D

    Statement I is correct but statement II is incorrect

Solution

Statement I: tRNAs read codons on the mRNA, and rRNA (within the ribosome) interacts directly with mRNA during translation. So the claim that they do not interact with mRNA is incorrect.

Statement II: RNAi is a well-established cellular-defence mechanism present in all eukaryotic organisms — correct.

Statement I incorrect, Statement II correct.
