The latent form of phage DNA that is present in lysogenic bacteria.
(pro´ fayj) • The noninfectious units that are linked with the chromosomes of the host bacteria and multiply with them but do not cause dissolution of the cell. Prophage can later enter into the lytic phase to complete the virus life cycle.
a bacterial virus that has integrated its DNA into the DNA of a bacterial cell
a bacterial virus the genome of which is residing in a bacterial host in a passive state, not expressing many viral functions or producing progeny virions
a bacteria virus (bacteriophage) in
a temperate phage in its integrated status
is a phage genome covalently integrated as a linear part of the bacterial chromosome.
Latent state of a phage genome in a lysogenic bacterium. Nagel et al. (eds), 1991
A prophage is a phage genome inserted as part of the linear structure of the DNA chromosome of a bacterium. A temperate phage integrated into the host chromosome or existing as an extrachromosomal plasmid. This is a latent form of a bacteriophage in which the viral genes are incorporated into the bacterial chromosomes without causing disruption of the bacterial cell.
