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:
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:
A
Both statement I and statement II are correct
B
Both statement I and statement II are incorrect
C
Statement I is correct but statement II is incorrect
D
Statement I is incorrect but statement II is correct
Explanation
Statement I is incorrect (tRNA and rRNA actively interact with mRNA in translation). Statement II is correct.
Detailed Solution
Statement I is false: During translation, tRNA binds mRNA via anticodon-codon base pairing, and rRNA aligns and binds mRNA. Statement II is true: RNAi is conserved across all eukaryotes as an innate defense against transposons and viral infection.
