NEET BIOLOGY

Detailed explanation-1: -Viruses have a protein coat called capsid, that encloses their genetic material.

Detailed explanation-2: -The Viral Capsid This protein coat is called a capsid, and the instructions for making the protein subunits of the capsid are encoded in the nucleic acid genome of the virus.

Detailed explanation-3: -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-4: -Many bacteria also surround themselves with a coat of protein armor, composed of a paracrystalline array of “surface layer proteins". In the case of archaebacteria, this protein coat is the often the primary structure that surrounds and shapes the cell.
