Concept

Problem: How does the presence of glucose in an E. coli's environment affect the transcription of the lac operon? Select all that apply.A. Increased glucose levels increase the level of cAMP, leading to more frequent transcription.B. Glucose will bind the repressor protein so that it can no longer cover the operator.C. Glucose will bind CAP, helping RNA polymerase bind more tightly to the operon's promoter.D. Increased glucose levels decrease the level of cAMP, leading to less frequent transcription.

FREE Expert Solution

In bacteria, genes of related function are grouped together as operons. These operons may either be inducible or repressible. Inducible operons are usually turned off while the repressible operons are usually turned on and both are only switched on/off with the appropriate signals.
