The steps are:
1-The phage binds to a bacterial surface.
2-Phage injects viral DNA in host bacterial cell.
3-Host DNA hydrolyses in pieces.
4-Phage DNA is now replicated and new phage coat proteins are synthesized.
5-The bacterial DNA is surrounded by phage coat protein.
6-Host bacterial cell lyses.
7-Bacterial DNA is injected in a bacterium by the phage.
8-Bacterial DNA integrates into the new bacterial host chromosome.
