Question

39. What would happen to the lac operon in the absence of allolactose? O The structural genes within the lac operon the will be constitutively transcribed. O The activator protein will be bound to the operator, which will turn on the structural gene behind it The repressor regulator protein binds to the operator and prevents the transcription of the O The catabolite activator protein becomes inactivated and no transcription occurs The cAMP level rises in the absence of aliolactose, which in turn inactivates the transcription.

Explanation / Answer
