NEET BIOLOGY

Detailed explanation-1: -A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) 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.

Detailed explanation-2: -The capsid is the protective layer that encapsulates viral genetic material in the extracellular environment. The capsid also mediates the entrance of the viral genetic material into a new host cell upon infection.

Detailed explanation-3: -cap·sid ˈkap-səd. : the protein shell of a virus particle surrounding its nucleic acid.

Detailed explanation-4: -A primary function of the capsid is to protect the viral genome from environmental conditions and ultimately to deliver the genome to the interior of a homologous host cell.

Detailed explanation-5: -(A) Virus capsids are composed of viral protein subunits that form structural units.
