Are you asking about "lambda phage"? (or is it my bad to remember it like that?)
If yes, as much as I know it is a phage (a virus) that lives in E.coli. It gets into the DNA of the host and dublicates with every division of the host.
That's all I know.

lambda phage has linear double-stranded DNA genome, which has 5' sticky ends (sequence on opposite strands are complementary and can therefore base pair with one another). Such pairing occurs within 2 minutes after penetration to convert a linear molecule into a circular one with two nicks. The biologically active lambda phage is circular rather than linear. What is more this phage has two types of life cycle: lytic and lysogenic and it is able to choose one of them depending on the conditions in which its host (E.coli) exist.
Hope it helps..
