Question

Consider the following statements. In eukaryotes
I. RNA polymerase I transcribes rRNAs
II. RNA polymerase II transcribes snRNAs
III. RNA polymerase III transcribes hnRNA
IV. RNA polymerase II transcribes hnRNA
Which of the statements given above are correct?

• A. I and II
• B. I and III
• C. I, II and IV
• D. II and III
• E. I and IV

Answer 1

The correct option is E I and IV

In eukaryotes, there are at least three RNA polymerases
RNA polymerase I, which transcribes rRNA (28S, 18S and 5.8S).
RNA polymerase II, which is responsible for the transcription of mRNA, the heterogeneous nuclear RNA (hnRNA).
RNA polymerase III, which is responsible for the transcription of tRNA, 5S rRNA and snRNA (small nuclear RNA).
Therefore, only I and IV are correct.
