An operon is a functional unit of genomic DNA containing a cluster of genes under the control of a single promoter. It is commonly found in prokaryotic organisms like bacteria and archaea. The genes within an operon are usually related in function and are transcribed together as a single mRNA molecule.

The classic example of an operon is the lac operon in Escherichia coli (E. coli), which controls the metabolism of lactose. The lac operon consists of three structural genes: lacZ, lacY, and lacA. ______ ___ __________ ____ _________ ___ _____ ________ _________.
