The operon in bacteria is a collection of genes with related function. When the proper signal is present, this operon can switch on or off and could express genes that are all involved in a specific function. For lac operon, this function is the digestion of lactose as a fuel source. An operon sequence is divided into three general parts: the promoter, the operator, and the genes that would be expressed.
