The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
Outer layer of a virus is called a capsid. It is the shell of protein which protects the nucleic acid, the brain of a virus. Capsid is composed of individual morphological units called capsomers.
