Operons

That Bio Doc talks all about how bacteria and other prokaryotes have organized genomes to contain operons, or multiple genes under the control of a single promoter. TBD uses the lac and trp operons to teach you how bacteria are able to efficiently regulate their gene transcription in response to changing environmental conditions through the activity of proteins called repressors.
