BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -There are all sorts of virus shapes and sizes. However, all virus particles have a protein coat that surrounds and protects a nucleic acid genome. 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: -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.
