Results in the death or lysis of the host cell.
Bacteriophage takes over the machinery of the cell, so viral replication and release occur.
Involves the incorporation of the viral genome into the host cell genome.
Phage becomes a prophage, integrated into the host genome.LYTIC AND LYSOGENIC CYCLES.
Later, the phage may reenter the lytic cycle and replicate itself.
Temperate viruses= integrate and remain latent.
