They have identical characteristics. <span />
1) Bacteriophage injects its DNA into the host cell
2) The DNA circularises
3) Viral gene activates the host cell's DNA synthetic machinery
4) Rapid reproduction of viral DNA occurs
5) Host makes viral capsomeres, allowing viral assembly to take place
6) Due to the large volume of new bacteriophages inside the host cell, the cell splits (cell lysis), releasing the new bacteriophages
