• explain what an operon is and how it functions

• An operon is a cluster of genes under the control of a single promoter, which allows for the coordinated regulation of gene expression in prokaryotes; it typically consists of structural genes, a promoter, and an operator, enabling the bacteria to efficiently respond to environmental changes.
