A gene cluster controlled by a single promoter that transcribes to a single mRNA strand

Explanation:

Operon are set of genes transcribed under the control of an operator gene. It consists of an operator, promoter, regulator and structural genes.

An operon is very important and is regarded as the functional unit of transcription and genetic regulation.

It is also known as a gene cluster controlled by a single promoter that transcribes to a single mRNA strand
