Regulation of Bacteriophage λ Replication

Bacteriophage λ is both a model for basic biological studies on the molecular level and a commonly used tool in molecular cloning. In this review we summarise the control of bacteriophage λ development, placing particular attention to the mechanisms involved in the “lysis or lysogeny” decision and the regulation of replication of phage λ DNA, as well as of plasmids derived from this phage.
