A model of gene expression within the lac operon is shown here. According to the model, how are genes regulated in the lac operon? Select ALL that apply.
es )
A)
Functional genes Z, Y, and A are continuously transcribed.
B)
In its natural configuration, the repressor protein cannot bind to the
operator
Functional genes Z, Y, and A are transcribed in the absence of a repressor
protein
D)
Functional genes Z, Y, and A are transcribed in the presence of lactose in
the environment.
E)
The gene that encodes for the repressor proteins is continuously
transcribed under all conditions.
