Summary Introduction
Introduction: Bacteria are single-celled prokaryotic microorganisms. A bacteriophage is also called as bacterial virus that is formed when a virus infects a bacterium. T2 and T4 are enterobacteria phages that infect and kill E. coli. They are also known as T-even phages because they are double stranded. T-even phages are commonly used as model organisms for various genetic studies. The experiments performed by Hershey and Chase using bacteriophages already proved that DNA is the genetic material of inheritance.
