Name the three RNA polymerases found in eukaryotic cells and mention their functions.

Explanation

There are three RNA polymerases found in eukaryotic cells:
(i) RNA polymerase-I : It is used to transcribes 5.8s, 18s and 28s RNA.
(b) RNA polymerase-II : It is involved in the transcription of MRNA precursors. It also catalyzes the formation of small nuclear RNA's and mRNA.
(c) RNA polymerase-III : It is used to transcribe transfer RNA (tRNA), some ribosomal RNA.
