  1. Lysogen

    A lysogen or lysogenic phage is a phage that can exist as a DNA in its dormant state within its host organism. A prophage is either integrated into the host bacteria's chromosome or more rarely exists as a stable plasmid within the host cell. The prophage expresses gene that repress the phage's lytic action, until this suppression is disrupted. Currently a variety of studies are being conducted to see whether other genes are active during lysogeny, examples of which include phage-encoded tRNA and virulence genes. Alternatively, lysogen can refer to a strain of bacterium that carries a prophage.
