A prophage is a bacteriophage (often shortened to "phage") genome that is integrated into the circular bacterial chromosome or exists as an extrachromosomal plasmid within the bacterial cell. Integration of prophages into the bacterial host is the characteristic step of the lysogenic … Meer weergeven Prophages are able to do a multitude of things within their respective bacterial strains. Prophages can increase the virulence potential of bacterial strains in both humans and plant pathogens as well as increase … Meer weergeven Upon detection of host cell damage by UV light or certain chemicals, the prophage is excised from the bacterial chromosome in a process called prophage induction. After induction, viral replication begins via the lytic cycle. In the lytic cycle, the virus commandeers … Meer weergeven Bacteriophage λ is able to undergo a type of recombinational repair called prophage reactivation. Prophage reactivation can occur by recombination between a UV-damaged infecting phage λ chromosome and a homologous phage genome integrated … Meer weergeven • Provirus Meer weergeven Zygotic induction occurs when a bacterial cell carrying the DNA of a bacterial virus transfers its own DNA along with the viral DNA (prophage) into the new host cell.
