The maltose operon contains genes that code for proteins that catabolize the disaccharide maltose. Similar to the Lacoperon, which is only efficiently transcribed in the presence of lactose, the maltose operon is only efficiently transcribed in the presence of maltose. How might induction of the maltose operon in response to maltose be achieved?
Choose one or more:
A. Maltose removes an activator from an operon.
B. Maltose causes a repressor to bind an operator.
C. Maltose removes a repressor from an operator.
D. Maltose causes an activator to bind an operon near the promoter.
