The function of capsid, nucleocapsid, tegument, and envelope proteins and their differences from cellular proteins. Introduction: Viruses are well-structured parasites that contain genome surrounded by a capsid. These microorganisms remain inert outside the body of the host but become functionally active once they gain entry into a living cell. There are variations in the structure among different viruses. These components of a viral structure perform various functions.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
