उत्तर
An operon is a cluster of structural genes with related functions.
Explanation:
An operon is a functional unit of DNA that contains a cluster of genes that are transcribed together into a single mRNA strand. This arrangement allows the cell to regulate a set of proteins with related metabolic functions, such as the enzymes needed to break down lactose, simultaneously. It typically consists of a promoter, an operator, and the structural genes themselves.
