A prokaryotic operon is composed of a series of adjacent genes under the control of

the same operator and promoter.

Explanation:

The operon is a part of the DNA that is functioning in nature and has a number of genes that are present in the cluster form and is controlled by a single and same operator and promoter. It is made up of a set of genes that are named as promoter, regulator, structural genes and some other. It plays an important role in the process of gene expression on the basis of the environment and some other conditions.
