RNA polymerase is an essential enzyme complex to carry out transcription, these enzymes are responsible for transcribing DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. This process is the first step of gene expression, and is called transcription. RNA polymerase binds to DNA in a very particular region or sequence, called a promoter.
