Which part of an operon is incorrectly matched with its function?
A) promoter-where RNA polymerase first binds to DNA
B) regulator-binds to the repressor protein
C) structural-makes mRNA by transcription
D) operator-if unbound, allows RNA polymerase to bind to DNA
E) all are incorrectly matched with its function
