Concept 2: The Lactose Operon
An operon is a cluster of bacterial genes along with an adjacent promoter that controls the transcription of those genes.
When the genes in an operon are transcribed, a single mRNA is produced for all the genes in that operon. This mRNA is said to be polycistronic because it carries the information for more than one type of protein.
