In a study of conjugation, an F+ E. coli donor carrying a plasmid with kanamycin resistance (KanR) and an intact tra operon was mixed with an F− recipient (KanS). After 30 min, cultures were plated on kanamycin. A parallel mixture included DNase I (100 U/mL) throughout the mating period. Colony counts (CFU/mL) on kanamycin were similar with and without DNase I. Which statement is most consistent with these observations?
