The maltose operon contains genes that code for proteins that catabolize the disaccharide maltose. Similar to the Lac operon, 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 a repressor from an operon with an efficient promoter. B. Maltose causes an activator to bind an operon with an efficient promoter. C. Maltose causes an activator to bind an operon with an inefficient promoter. D. Maltose causes a repressor to bind an operon with an efficient promoter. E. Maltose removes an activator from an operon with an inefficient promoter.

The correct answers are option A. "Maltose removes a repressor from an operon with an efficient promoter" and option C. "Maltose causes an activator to bind an operon with an inefficient promoter".

Explanation:

Two ways at which maltose operon works in the presence of maltose is by maltose removing a repressor from an operon with an efficient promoter and by maltose causing activator to bind an operon with an inefficient promoter. Maltose removes the repressor malR (Maltose operon transcriptional repressor) with an efficient promoter called malE.  Additionally, maltose causes an activator to bind an operon with an inefficient promoter known as malT.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
