Below is the nontemplate sequence of the three lac genes lacZ, lacY and lacA. lacZ (the gene for β-galactosidase) is marked with red color, lacY (the gene for lactose permease) with green color and lacA (the gene for galactoside O-acetyltransferase) with blue color. White bases belong to untranslated regions. Note how an untranslated region separates lacZ from lacY, and lacY from lacA.

The sequence starts with the first base transcribed from the lac promoter (here numbered 1) and ends with the last base of the lacA gene (here numbered 5095). The 5'-end is at base 1 and the 3'-end is at base 5095. The lac operator near the 5'-end is marked with bold text. The X-axis shows base numbers in steps of tens and the Y-axis shows base numbers in steps of hundreds. The complete transcribed sequence also contains an untranslated region after the lacA gene (after base number 5095), this region is not presented here (as I currently don't know how many bases it includes).

The sequence data was obtained from BioCyc's genome browser with E. coli K-12 substrain MG1655 as the selected organism, where the 5'-end and 3'-end of the below sequence corresponds to base pair 366343 and 361249 in the genome browser. The beginning and end of each gene is as shown in the genome browser.
