Which enzyme will be produced in a cell where a nonsense mutation is present in the lac operon?

A bacterial cell is mutated and cannot create the repressor protein associated with the Lac operon. How will this affect the functioning of the Lac operon?

What would happen if the operator sequence of the lac operon contained a mutation that prevented the repressor protein from binding the operator?  (Explain what would happen both in the presence and absence of lactose)

What does the lac operon consist of? How is the operator switch turned on and off in the expression of genes in this operon? Explain.

A mutation prevents the catabolite activator protein (CAP) from binding to the promoter in the lac operon. What will the effect of this mutation be on the transcription of the operon?

Under what conditions would you expect to see high levels of expression of the structural genes in the lac operon? Group of answer choices Lactose is absent and glucose is absent Lactose is absent and glucose is present Lactose is present and glucose is present None of these Lactose is present and glucose is absent

a mutation that leads to a nonfunctional adenylate cyclase enzyme would lead to what expression occuring at what levels to which operon?

If glucose is not available, but lactose is available from the environment, what is the status of transcription of the lac operon genes? Explain your answer from both an evolutionary perspective and in terms of negative and positive regulation of the operon?

The lac operon consists of regulatory regions such as the promoter as well as the structural genes lacZ, lacY, and lacA, which code for proteins involved in lactose metabolism. What would be the outcome of a mutation in lacA?

Will the Lac Operon be turned off or on if the allolactoase is not present?
