Question

Why is lysogeny advantageous to a bacteriophage?

Answer 1

Bacteriophages capable of a lysogenic life cycle are calles temperate phages. When a temperate phage infects a bacterium, it can either replicate by means of the lytic life cycle and cause lysis (bursting) of the host bacterium. When the host cell lyses, new phages are released into the environment to infect other cells.

Answer 2

a bacteriophage suffers lysis and causes the bursting of E.coli...it is advantageous to the phage cause it suffers mutation when the phages is regenerated just before nursting of the phage they suffer mutation which later results in evolution....
