The multiplication process of temperate phage is called Lysogenic cycle and the multiplication of virulent phage is called lytic cycle.Lysogenic phase
1. The viral genome or its complementary DNA gets integrated with the host DNA. It is called prophage or provirus.
2. The host DNA is not hydrolysed during lysogenic phase
3. The prophage or provirus replicates only once along with the replication of host genome so that a single particle is transferred to a daughter cell.
4. The cellular machinery of the host is only slightly disturbed.
5. The virus is non virulent or temperate.
6. The host cell does not get lysed.
7. Virus particles are liberated only rarely.
1. The viral genome does not integrate with host DNA.
2. The host DNA is often hydrolysed in the lytic phase
3. The viral genome replicates repeatedly and forms a number of copies in the same host cell.
4. The cellular machinery of the host is completely taken over by the viral genome.
5. The virus is virulent
6. The host cell undergoes lysis
7. A number of virus particles are liberated when the host cell become lysed.
