And our coding section actually consists of sequence of DNA that code for certain types of polypeptides for certain types of proteins. So this is our opera. It consists of our control sites and also consists of the structural genes. Now, any given unit, any given operon itself also is found next to a regulatory gene. And the regulatory gene basically consists of the sequence of DNA that codes for the repressor or activator. So every single opera next to the opera contains the regulatory gene that codes for either the repressor or the activator that is involved within that opera.
