test 1 number 34.
question is which of the following best describes gene regulation and expression in an inducible system?
A. the repressor binds to the operator, forming a barrier that prevents gene from being transcribed.
B. the repressor is inactive until it combines with the corepressor allowing gene to be transcribed.
C. the inducer-repressor binds to the operator allowing genes to be transcribed.
D. the repressor-corepressor binds to the operator and represses enzyme synrhesis
E. regulation is tina constant state of transcription.
I know answers A. but i dont understand why D is wrong..
Any thought??
thanks
