Summary Introduction
Introduction:
Virus multiplication is a process in which the infection of viral particles on the host cells. During the infections, it introduces the viral genetic material (DNA or RNA) to the host target cell with the help of some essential proteins. After the infection, it replicates their gene products. The bacteriophage replication is occurs in two ways either lytic or lysogenic cycles.
