Briefly describe the difference between the lytic cycle of virulent phages and the lysogenic cycle of temperate phages. Virulent phages reproduce strictly by the lytic cycle and ultimately result in the death of the host bacterial cell. During the lytic cycle, a virus injects its genome into the host cell.The genome directs production and assembly of new viral particles. A viral enzyme is produced and breaks open the cell, releasing new viral particles into the environment.Temperature phages can utilize either the lytic or lysogenic cycle. The infection cycle begins when a viral particle injects its genome into the host cell.n the lysogenic cycle, the viral genome integrates into the host chromosome as a prophage. The inactive prophage can remain part of the bacterial chromosome for an extended period and is replicated along with the bacterial chromosome prior to cell division.
This is called the lytic cycle and is a process of viral replication that leads to formation of viral progeny and the potential lysis, or destruction, of the host cell. Viruses that are in the lytic cycle are termed virulent as opposed to temperate.Animal viruses undergo the lytic cycle as well.ometimes, the viral genome will actually integrate itself into the host's chromosomes. When the viral genome is integrated into, and replicates along with, the host's genome, we call this viral genome a provirus. A provirus is a term specific to viruses that infect animal cells.
