In the process of transcription in Eukaryotes, the RNA polymerase I transcribes :-
In eukaryotes, there are at least three RNA polymerases In the nucleus.
RNA polymerase I transcribes → rRNAs {28S, 18S and 5.8S}
RNA polymerase II transcribes → hnRNA {precursor of mRNA}
RNA polymerase III transcribes → tRNA, 5srRNA and snRNAs
