Hfr strains that differ in integrated F factor orientation and site of integration are used to construct consolidated bacterial chromosome maps. The data below show the order of gene transfer for five strains.

Hfr Strain       Order of Gene Transfer (First → Last)
Hfr A                oriT–thr–leu–azi–ton–pro–lac–ade
Hfr B                oriT–mtl–xyl–mal–str–his
Hfr C                oriT–ile–met–thi–thr–leu–azi–ton
Hfr D                oriT–his–trp–gal–ade–lac–pro–ton
Hfr E                oriT–thi–met–ile–mtl–xyl–mal–str

Draw a consolidated map of the bacterial chromosome. (Hint: Begin by placing the insertion site for Hfr A at the 2 o'clock position and arranging the genes thr–leu–azi- . . . in clockwise order.)
