Detailed Solution
Eukaryotic nuclei have three types of RNA polymerase:
RNA polymerase I transcribes rRNAs (28S, 18S and 5.8S).
RNA polymerase II transcribes the precursor of mRNA (hnRNA).
RNA polymerase III transcribes tRNA, 5S rRNA and snRNAs.
So 3 types of RNA polymerase are required in the nucleus. (Prokaryotes have only one.)
