Figure 7-50Eucaryotic gene regulatory proteins often assemble into complexes on DNA

Seven gene regulatory proteins are shown in (A). The nature and function of the complex they form depends on the specific DNA sequence that seeds their assembly. In (B), some assembled complexes activate gene transcription, while another represses transcription. Note that the red protein is shared by both activating and repressing complexes.
