You have identified an operon on a new strain of E. coli that carries three genes involved in capsule biosynthesis, as well as a regulatory gene. After careful analysis of the operon and its flanking DNA sequences, you suspect that the operon is located on a PAI that is a lysogenic prophage. What possible evidence might have led you to propose this?
