It is comprised of an operator, a promoter, and one or more structural genes that are transcribed into one polycistronic mRNA.peron. Definition. noun, plural: operons.

In prokaryotes, DNA-binding proteins regulate genes by controlling transcription. An operon is a group of genes that are regulated together. An example is the lac operon in the bacterium E. coli : â¶ This group of three genes must be turned on together before the bacterium can use lactose as food. sequence of three bases on a tRNA molecule that is complementary to a sequence of bases on an mRNA molecule 10.
