When do bacteria normally regulate gene expression? during transcription
How is the lac operon induced? lactose combines with lac repressor to inactivate it--RNA polymerase can then bind to the promoter and transcribe the lac operon
How is the tryptophan operon repressed? tryptophan binds to trp operon aporepressor fo form active complex--binds to trp operator and prevents RNA polymerase binding and transcription
Describe feedback inhibition associated with repressible operons where end product of peron pathway makes a complex with aporepressor to inhibit transcription
Give 2 ways that inducible and repressible expression control differs inducible--turn on expression--repressible--turn expression off--repressible systems have fine control over how much expression occurs
