E. coli cells were spread on an agar plate, producing 1000 colonies. The colonies are replica plated on two agar plates containing the antibiotic kanamycin and one agar plate without antibiotics. All of the colonies are able to grow on the agar plate without antibiotic but only 4 colonies are able to grow on each of the agar plates containing kanamycin. You notice that the four colonies that grew on each of the kanamycin containing plates are in the exact same position. This demonstrates
