So when glucose concentration is high RNA polymerase will bind to the promoter region so region number one and when RNA polymerase binds to our promoter region it will basically transcribe this DNA molecule into an mRNA molecule and then that mRNA molecule will be used by the ribosome to basically synthesize the repressor protein. And once a repressive protein is formed it will go on and bind to site number five. So site number five is one of the control sites. It's known as our operator region. And once the repressive protein binds to the operator region by using electric forces once it binds it basically will block the process of transcription of these genes here. So once formed, the repressive protein binds the operator region and blocks the RNA polymerase from transcribing, the mRNA molecule that codes for the beta Galacticase, as well as these other two types of genes.
