The majority of viruses have capsids with either helical or icosahedral structure. Some viruses, such as bacteriophages, have developed more complicated structures due to constraints of elasticity and electrostatics.
All viruses have a capsid or head region that contains its genetic material. The capsid is made of proteins and glycoproteins. Capsid contruction varies greatly among viruses, with most being specialized for a particular virus's host organism.Some viruses, mostly of the type infecting animals, have a membranous envelope surrounding their capsid.apsid contruction varies greatly among viruses, with most being specialized for a particular virus's host organism.
