In transcription in eukaryotes, heterogenous nuclear RNA (hnRNA)is transcribed by

Options

A. RNA polymerase I
B. RNA polymerase II
C. RNA polymerase III
D. all of these.

Answer

B

Explanation

(b) : Eukaryotes have three RNA (28S, 18S and 5.8S) whereas RNA polymerase II is localised in the nucleoplasm and used for hnRNA, mRNA and RNA polymerase III is localised in the nucleus, possibly the nucleolar-nucleoplasm interface and transcribes for tRNA , 5S rRNA and snRNAs.
