What Does The Enzyme RNA Polymerase Do?

The enzyme RNA polymerase is a central component of the cellular mechanism that transcribes the code in a DNA molecule so that it can be used for form the template to make a protein. The protein is made from the DNA that makes up a single gene. This is a central dogma in biology – one gene codes for one protein only.

Transcription is the transfer of the genetic information from DNA to a short-lived molecule - messenger RNA. The enzyme RNA polymerase binds to part of the DNA that corresponds to the beginning of a gene and starts to make a strand of mRNA. The RNA polymerase makes an elongating chain of RNA nucleotides that form an RNA molecule. The completed mRNA molecule is released from RNA polymerase - DNA complex and then moves from the nucleus into the cytoplasm to be worked on by the ribosomes to produce the final protein

RNA polymerase facilitates the expression of a gene – without this important protein molecule, genes could not be converted to proteins for use by living cells.
