===Bacteriophages===

A  bacteriophage is a term used to describe a virus that is able to infect  a bacterial cell and they can be either virulent or temperate depending  on their method of replication. Virulent bacteriophages undergo a lytic  cycle within the bacterium which eventually results in the production  of bacteriophage progeny from the cell and the lysis of the bacterium.  <br />

A bacteriophage can be composed of either DNA or RNA  and iehter single or double stranded. The capsid (outer protective layer) of the bacteriophage often remains outside the bacterial cell  after the viral nucleic material has entered the cell cytoplasm. The  host specificity of bacteriophages is related to the chemical affinity  between attachment structures on the surface of the bacteriophage capsid  and the receptors on the surface of the bacterium. <br />

Genetic  variation can occur in a number of ways and the genotype of the  bacteria determines its inheritable potential. Below are the main ways  that genetic mutation can occur in bacteria;
