In What process does a phage kill its host?

A phage kills its host through the lytic cycle, where it attaches to the bacterial cell, injects its genetic material, and hijacks the host's cellular machinery to replicate its own components. This leads to the assembly of new phage particles within the host. Eventually, the host cell becomes overwhelmed and lyses, or breaks open, releasing the newly formed phages to infect other cells. This process results in the destruction of the host bacterium.
