Definition Two major component of a virus particle are viral genome and the protein coat. The protein coat is its capsid. The capsid protein subunits wind around the core genome to form this rod-like structure. According to the number of subunits possessed by capsomers, they are called dimers (2), trimers (3), pentamers (5), or hexamers (6). The capsids are made from capsomeres, or protein subunits.
