Question

What are the types of RNA polymerases in eukaryotes?

Answer 1

RNA polymerase: The enzyme which transcripts the double-stranded DNA sequence into a single-stranded RNA, i.e transcription.

Types of RNA polymerases:

1. RNA polymerase I or RNA pol I: The polymerase enzyme which transcribes the ribosomal RNA genes.
2. RNA polymerase II or RNA pol ll: The polymerase enzyme transcribes genes of messenger RNA, microRNA, and small interfering RNA.
3. RNA polymerase III or RNA pol llI: The polymerase enzyme transcribes genes of translation RNA and 5S rRNA.
