To propose a hypothesis: To compare the structures of tobacco mosaic virus and influenza virus. Introduction: Virus is a distinctive class of microscopic organisms that are infectious in nature. They are typical parasites that can replicate only inside a living host like bacteria, animals, plants, etc. The viral genome is made of nucleic acid , DNA or RNA, which can be either single or double stranded, circular or linear. The nucleic acid is enclosed within a protective protein coat known as capsid. Capsomere is structurally made of individual protein subunits that self-assemble to form a capsid. Virus can infect both plants (e.g. tobacco mosaic virus) and animals (e.g. influenza virus). In some virus the virus capsid is surrounded by a structure called as envelope. This viral envelope is made of lipids and proteins and helps in viral attachment and transfer of genetic material to host.
