When a Structural Gene Is Under Negative Inducible Control, What

Multiple Choice

When a structural gene is under negative inducible control, what would be the result of a mutation that eliminates the repressor protein?

A) The structural gene will be constitutively expressed due to the lack of negative inducible control.
B) The transcription of the structural gene will not be affected, as a repressor is not required.
C) The mutation will lead to activation of an activator upon the lack of a repressor protein, which will allow the transcription to continue.
D) As the transcription will require a repressor protein, the transcription will be turned off.
E) More cAMP will be produced in a cell to compensate for the lack of a repressor protein.
