Here's why:
* Operon: An operon is a unit of genetic material that functions as a single regulated unit. It includes a cluster of genes under the control of a single promoter.
* Related Functions: The genes within an operon typically code for proteins involved in a specific metabolic pathway or cellular process.
* Control Sequences: The operon includes a promoter (where RNA polymerase binds to initiate transcription) and an operator (a DNA segment where regulatory proteins can bind to control gene expression).
Example: The lac operon in *E. coli* is a classic example. It contains genes for lactose metabolism and is regulated by the presence or absence of lactose in the environment.
