Abstract
Viruses are smallest, ultramicroscopic, non-cellular, obligate intracellular infectious agents that cannot reproduce outside their host cell. Their genome contains either DNA or RNA as genetic material. Their genome is enclosed in a protein shell known as capsid, which may be surrounded by a lipid containing membrane called envelope. The entire infectious unit is called “Virion”- an extracellular infectious virus particle. Viruses are connecting link between living and non livings because it act as non living particle outside the host cell while reproduce inside host cell like living organisms does.
