So the synthesis of the protein, the enzyme beta Galacticidase is controlled by a special type of operon found on the DNA of the prokaryotic cell known as the lac operon. So let's take a look at the lac opera. The lac opera is basically this section here. So the lac operon consists of two sections. We have the regulatory section which is basically this section here and we have our coating section. The coating section basically consists of three genes that each code for a specific type of enzyme that is involved in the breakdown of lactose.
