Summary Introduction
Introduction: Those organisms which form the connecting link between the living and non-living organisms are called “virus”. The size of the virus is very small and varies from 20 to 300 nm. Nutrition obtained by the virus from the body of the host is later contributed to the production of its clone copies. The absence of the host body in the life cycle of the virus makes the virus inactive.
