Figure 3.6Two ways in which RNA polymerases bind to their promoters

(A) shows the direct recognition of the promoter by the RNA polymerase, as occurs in bacteria. (B) shows recognition of the promoter by a DNA-binding protein which forms a platform onto which the RNA polymerase binds. This indirect mechanism occurs with eukaryotic and archaeal RNA polymerases.
