The orange part is the coding region for the regulatory protein for the lac operon, lacI. The pink/purple/blue part is the lacZYA operon, but only the open reading frames (ORFs) for lacZ and lacY are shown. Below describes more specifically what each element is: Orange rounded rectangle: LacI promoter Light orange rectangle: LacI ORF Dark orange rectangle: LacI terminator Pink rounded rectangle: LacZYA promoter Purple triangular thing: LacZYA operator Light blue rectangle: LacZ ORF Blue rectangle: LacY ORF Dark blue rectangle: LacZYA terminator Light blue blob: RNA polymerase Light red oval: B-galactosidase (LacY product) Light purple tube thing: Lactose permease (LacZ product) Gray triangular thing: LacI repressor protein Black squiggles: mRNA Yellow dot: Lactose molecule Dark green: Plasma membrane Light green: Bacterial cytoplasm
