Options
- A(A)-(II), (B)-(I), (C)-(III)
- B(A)-(I), (B)-(II), (C)-(III)
- C(A)-(III), (B)-(II), (C)-(I)
- D(A)-(III), (B)-(I), (C)-(II)
Correct answer
D. (A)-(III), (B)-(I), (C)-(II)
Step-by-step solution
In eukaryotes, there is a clear division of labour among the RNA polymerases in the nucleus. RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S). RNA polymerase II transcribes the precursor of mRNA, the heterogeneous nuclear RNA (hnRNA). RNA polymerase III is responsible for the transcription of tRNA, 5S rRNA, and snRNAs. Therefore, the correct match is (A)-(III), (B)-(I), (C)-(II). Answer: (A)-(III), (B)-(I), (C)-(II)
