Detailed explanation-1: -The correct option is D capsomeres. A virus is a nucleoprotein which consists of the DNA or RNA as genetic material and protein coat called capsid. The protein coat (capsid) is made up of small subunits called capsomeres which protects the nucleic acid.

Detailed explanation-2: -A virus is made up of genetic material that is encased with a protective protein coat called the capsid. The capsid also helps the virus to infect host cells by binding to the host receptor proteins and releasing its genetic material.

Detailed explanation-3: -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. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres.

Detailed explanation-4: -The capsid enclosing nucleic acid is referred to as nucleocapsid, which can be considered as an infectious and functional virus. Envelope-In some viruses, the nucleocapsid is covered with another layer of proteins and fats called as glycoproteins.

Detailed explanation-5: -Virus particles contain the viral genome packaged in a protein coat called the capsid. For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells.
