Detailed explanation-1: -Each virus possesses a protein capsid to protect its nucleic acid genome from the harsh environment. Virus capsids predominantly come in two shapes: helical and icosahedral.
Detailed explanation-2: -The main function of virus coat protein is formation of the capsid that protects the virus genome against degradation. However, besides the structural function, coat proteins have many additional important activities in the infection cycle of the virus and in the defense response of host plants to viral infection.
Detailed explanation-3: -Coat proteins allow the selective transfer of macromolecules from one membrane-enclosed compartment to another by concentrating macromolecules into specialized membrane patches and then deforming these patches into small coated vesicles.
Detailed explanation-4: -The protein coat which surrounds the genome (DNA or RNA molecules) of a virus is called the capsid. Capsid functions as a shell to protect the viral genome from degradative enzymes such as nucleases and also helps in the attachment of the virus to specific receptors exposed on the surface of their target host cells.
