Hey Mate
Regulator gene regulates the expression of structural genes by its protein product that is mostly transcription factors. These transcription factors bind to the operator region which is located just upstream the binding site of the RNA polymerase and hence prevent the binding and transcription. Enhancers are the upstream activation sites present within promoter and interact with protein other than RNA polymerase thereby regulating the activity of the promoter. Receptor site is present upstream of the transcription unit and is involved in recognition; it does not take part in transcription. Promoter is a cis-acting site present physically continuous with transcription unit and provides binding site for RNA polymerase enzyme.
