RNA polymerase. The RNA polymerase is the enzyme that helps in transcription. It helps in the synthesis of mRNA, which basically copies DNA sequence into RNA sequence. RNA polymerase works from the 3’ end to the 5’ end of the template strand of DNA. This helps to create the new growing strand growing from 5’ to 3’ direction. In prokaryotes, RNA polymerase is made up of subunits, including a sigma factor but in eukaryotes.

There are 5 RNA polymerases. RNA polymerase I produce the largest amount of RNA. They synthesize ribosomal RNA, which forms most parts of ribosomes. RNA polymerase II functions in transcription. It is involved in the synthesis of mRNA. RNA polymerase III synthesizes transfer RNA. RNA polymerase IV and V are found only in plants.
