Vedclass · Answer

(A) An operon is a functional unit of $DNA$ containing a cluster of genes under the control of a single promoter. It typically consists of structural genes,an operator,and a promoter. While the regulatory gene is often associated with the operon,it is technically located outside the operon unit itself. However,in the context of standard multiple-choice questions,the structural genes,promoter,and operator are the core components. Since the provided options are limited,the most accurate description of the functional unit is the combination of structural genes,promoter,and operator. Given the options provided,there appears to be a slight discrepancy in terminology; however,option $A$ is the intended answer as it lists the primary components of the operon system.
