Viral Replication
The lytic and lysogenic cycles are cycles of viral replication.
Lytic Cycle
Viruses need genetic material, something to insert that material, and a membrane. The virus takes over all metabolic activities of a cell causing the host cell to die. The bacteriophage will attach itself to the host cell by latching on to a reciprocity. It then injects its DNA into the host cell. Then replication takes place where they break down the cell's DNA and take over the metabolic activities. The viruses DNA directs the production of new viruses. The host cell then burst open letting out 100-200 new virus particles.

Lysogenic Cycle
In this cycle, the viral genome is replicated without destroying the host cell. First, the phage attaches to the host cell and injects its DNA. Then, the viral genome enters the cell and makes part of the host cell's genomes. When the host cell's DNA is copied, so is the viral DNA. When the cell divides, the virus chromosomes are transmitted to the daughter cells. After they are transmitted, the viral genomes can enter the lytic cycle at any given time and destroy the new host cell made after the cell division.
