<virology> The ability of some phages to survive in a bacterium as a result of the integration of their DNA into the host chromosome. The integrated DNA is termed a prophage. A regulator gene produces a repressor protein that suppresses the lytic activity of the phage, but various environmental factors, such as ultraviolet irradiation may pre...

The ability of some phages to survive in a bacterium as a result of the integration of their DNA into the host chromosome. The integrated DNA is termed a prophage. A regulator gene produces a repressor protein that suppresses the lytic activity of the phage, but various environmental factors, such as ultraviolet irradiation, may prevent synthesis of the repressor, leading to normal phage development and lysis of the bacterium. The best example of this is the lambda bacteriophage.

Type: Term Pronunciation: lī-soj′ĕ-nē Definitions: 1. The phenomenon by which a bacterium is infected by a temperate bacteriophage with DNA that is integrated into the bacterial genome and replicates along with the bacterial DNA but remains latent or unexpressed; triggering of the lytic cycle may occur spontaneously or by certa...

lysogenicitynoun the condition of a host bacterium that has incorporated a phage into its own genetic material; `when a phage infects a bacterium it can either destroy its host or be incorporated in the host genome in a state of lysogeny` Found on https://www.encyclo.co.uk/local/20974
