If the number of phage particles is two or more, it is more likely to produce lysogney. And as the numbers of phage per cell become lower and lower, the tendency toward lytic infection increases, and as it becomes higher and higher, the likelihood of lysogeny similarly increases.

FENl is an exo-jendonuclease that recognizes the structure created when one strand of DNA is displaced from a duplex as a "flap." In mammalian replication it cleaves at the base of the flap to remove the RNA primer.
