Definition of Rna Polymerase



RNA polymerase is an enzyme that catalyzes the process of transcription (a process by which a strand DNA is converted into the strand of messenger RNA). The RNA polymerase is responsible for copying the information present in the sequences of DNA into that of RNA and it is known to be a complex molecule which is consisted of protein subunits.

 


RNA polymerases are normally found in almost all species but their number and composition might alter across the taxa. The prokaryotes have a single type of RNA polymerase whereas the eukaryotes have 3 types of it.
