ohaa [14]

An operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.

operon is a functional unit of gene.

This cluster of gene transcribed together to give a messenger RNA which further give rises to protein.

operator in operon is the site where repressor binds.

promoter is where Mrna binds , where our genes are transcribed

structural genes, they code for the enzyme that are involved in this metabolic pathway.

Operons have an important role to play as they produce protein for the cell this serves them energy, the protein is produced only when energy is required.
