Thinking of lactose operon regulation, what happens when E. coli is grown in medium with glucose and lactose? Group of answer choices neither Cap/cAMP activator nor LacI repressor are bound to a regulatory DNA sequence. LacI repressor is bound to the OPERATOR sequence but Cap/cAMPactivator is not. Cap/cAMP activator is bound to the CAP motif but LacI repressor is not. both Cap/cAMP activator and LacI repressor are bound to the OPERATOR sequence.

1) 4pts - The presence of glucose in the environment prevents lots of lac operon expression, while glucose’s absence greatly increases expression – discuss how ATP concentration, adenylyl cyclase, and CAP/cAMP and holoenzyme increase lac operon expression. 2) Discuss how promoters, enhancers and the TF proteins that interact with them are used in eukaryotic cells to control transcription of housekeeping genes versus cell specific/regulated genes? Be specific about everything’s role – what binds where and does what! A) 4pts -...
