The lac operon regulates expression of the three lac genes by regulating the efficiency of that process. Negative Control of Transcription: Immediately upstream of the three lac genes is a fourth gene which is responsible for negative regulation of the operon.This gene expresses a protein called the lac repressor. The repressor can bind to a short sequence of the lac promoter.t the 5' end of the lac operon is a promoter. The promoter is the site where RNA polymerase binds to DNA to initiate transcription. The amount of mRNA produced from a given operon depends on the efficiency of promoter recognition.
