capsid

 [kap´sid]
the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers. According to the number of subunits possessed by capsomers, they are called dimers (2), trimers (3), pentamers (5), or hexamers (6).

capsid

A protein coat that covers the nucleoprotein core or nucleic acid (RNA, DNA) of a free virus particle or phage, which may have icosahedral symmetry and itself be enclosed in an envelope—e.g., Togaviridae. It is composed of an integer multiple of 60 subunits, which self-assemble in a pattern typical for a particular virus.

It is within these upper cell layers that the virus initiates stages of its life cycle: inducing host cell replication and division to produce multiple copies of viral DNA, forming the viral capsid, viral assembly, and finally, release of the virus.
