Question

Match the following RNA polymerases with their transcribed products:

Column I
(a) RNA polymerase I
(b) RNA polymerase II
(c) RNA polymerase III

Column II
(i) rRNAs
(ii) tRNA
(iii) hnRNA

Accepted Answer

According to the text regarding transcription in eukaryotes, there is a division of labour among the three 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 transcription of tRNA, 5srRNA, and snRNAs .
Therefore, the correct matching is a-(i), b-(iii), c-(ii).
