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).

cap·sid

(kap'sid),
Protein coat of a virus. See: virion.

capsid

(kăp′sĭd)
n.
The protein coat that constitutes the shell of a virus particle.

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.

vi·ri·on

(vī'rē-on)
The complete virus particle that is structurally intact and infectious.

capsid

The protein coat that encloses the genome of a virus.

capsid

the protein coat of a virus.

Capsid

The outer protein coat of a 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.
