The Transcription Process
... Polymerases are large enzymes composed of approximately a dozen subunits, and when active on DNA, they are also typically complexed with other factors. In many cases, these factors signal which gene is to be transcribed. Three different types of RNA polymerase exist in eukaryotic cells, whereas bact ...
