The virus genomic component inside the capsid, along with occasionally present virus core protein, is called the virus core. The capsid and core together are referred to as a nucleocapsid (cf. also virion). Capsids are broadly classified according to their structure.
The virus wraps its delicate nucleic acid with a protein shell known as the capsid, from the Latin capsa, meaning "box," in order to shield it from this hostile environment. Similar to how numerous bricks come together to form a wall, the capsid is made up of one or more distinct protein types that repeatedly repeat to form the whole capsid.
The full assembled capsid structure of the satellite tobacco mosaic virus, with the monomer shown above at the bottom of the highlighted pentamer. The remainder of the protein chains are shown in purple and the RNA in the interior of the capsid is shown in brown. The axis of the jelly roll in this single jelly roll capsid is parallel to the ...
Simplified diagram of the structure of a virus. A virus particle, also called a virion, consists of genes made from DNA or RNA which are surrounded by a protective coat of protein called a capsid. [23] The capsid is made of many smaller, identical protein molecules called capsomers.
The capsid and entire virus structure can be mechanically (physically) probed through atomic force microscopy. [43] [44] In general, there are five main morphological virus types: Helical These viruses are composed of a single type of capsomere stacked around a central axis to form a helical structure, which may have a central cavity, or tube ...
The capsomere is a subunit of the capsid, an outer covering of protein that protects the genetic material of a virus. Capsomeres self-assemble to form the capsid. [1] In this diagram of an Adenovirus, the capsid molecules are clearly visible. Subunits called protomers aggregate to form capsomeres. Various arrangements of capsomeres are: 1 ...

Many copies of a single viral protein or a number of different viral proteins make up the capsid, and each of these viral proteins are coded for by one gene from the viral genome. The structure of the capsid allows the virus to use a small number of viral genes to make a large capsid. [3]
