what is a capsid
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers.The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres.The capsid encloses the genetic material of the virus.uring this process, new capsid subunits are synthesized according to the genetic material of the virus, using the protein biosynthesis mechanism of the cell. During the assembly process, a portal subunit is assembled at one vertex of the capsid.
