Quizplus · Accepted Answer

A prokaryotic operon is composed of a series of adjacent genes under the control of the same operator and promoter. The operator is the site where regulatory proteins bind to control gene expression, and the promoter is the site where RNA polymerase binds to initiate transcription. Having the same operator and promoter allows for coordinated regulation of all the genes within the operon.
