WebHelical Capsid: The capsid is the outer protein shell of a virus that surrounds the nucleic acid core. A virus with a helical capsid has a helical nucleic acid structure with capsid … The proteins making up the capsid are called capsid proteins or viral coat proteins (VCP). The capsid and inner genome is called the nucleocapsid. Capsids are broadly classified according to their structure. The majority of the viruses have capsids with either helical or icosahedral structure. Meer weergeven 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.
