Which of the following figures correctly depicts the interactions at the lac operon when lactose is NOT being utilized? (The legend below defines the shapes of the molecules illustrated in the options.) A key with three figures, RNA polymerase is a triangular oval. Repressor Protein is a semicircle with a rectangle missing from the flat side of the semicircle. Lactose is a semicircle that has an additional rectangle protruding from the flat side of the semicircle. Repressor Protein and Lactose are complementary, and create a full circle when they are together.
