A VIRUS is non-cellular, obligatory parasite (i-e; host dependent) , self-replicating genetic element consisting of DNA and RNA with no metabolic capability, but capable of transmission from host cell to host cell via a vector stage called VIRION in which the nucleic acid is encapsulated in protein coat. VIRUS Any of various simple submicroscopic particles of plants, animals and bacteria that often cause disease and that consists essentially of a core of RNA or DNA surrounded by a protein coat. Unable to replicate without host cell, viruses are typically not considered living organisms. VIRION A complete virus particles, consisting of RNA or DNA surrounded by a protein shell and consisting the infective form of a virus. httpswww.youtube.com/...obs
