1. Answer the following completely and in detail.

a) Draw, clearly label, and describe how binding of the trp corepressor to its repressor alters repressor function and transcription in E. coli.

b) Draw, clearly label, and describe the binding of RNA polymerase, repressors, and activators to the lac operon when both lactose and glucose are scarce. What is the effect of these scarcities on transcription of the lac operon?

c) Suppose that a certain mutation in E. coli changes the lac operator so that the active repressor cannot bind. How would this affect the cell's production of B-galactosidase?

THANK YOU!
