Summary Introduction
Introduction:
Virus that infect and replicate inside the bacteria is called bacteriophage or phage. Bacteriophages replicate their genetic material by lytic and lysogenic cycles. During the replication process, it injects the viral genetic material (DNA or RNA) to the host target cell with the help of some essential proteins and helps to replicate the number of copies.
