What would be the result of a mutation that deactivates the regulatory gene of a repressible operon in an Escherichia coli cell?

Question

Quizplus · Accepted Answer

A repressible operon is normally turned on, but can be inhibited by a regulatory protein called a repressor. The regulatory gene codes for the repressor protein. If the regulatory gene is mutated and inactivated, the repressor protein cannot be produced, and thus cannot bind to the operator to stop transcription. This results in continuous transcription of the structural gene controlled by that regulator.
