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.
In order to produce new copies of itself, a virus must use the host cell's reproductive machinery.. The newly made viruses then leave the host cell, sometimes killing it in the process, and proceed to infect other cells within the organism.he second pathway available to viruses is called the lytic cycle. In the lytic cycle, the virus first attaches itself to the surface of the host cell. It then makes a hole in the cell membrane and injects its genetic material (DNA or RNA).
