Detailed explanation-1: -A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat.
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: -The outer protein coat of a virus is known as the capsid. It consists of several oligomeric structural subunits made of a protein called protomers which cover the nucleic acid which is present in the virus and protects it when virus inserts itself into the host.
Detailed explanation-4: -Viruses have a protein coat called capsid, that encloses their genetic material.
Detailed explanation-5: -Viruses contain either RNA or DNA as their genetic material. DNA in most organisms is a double-stranded structure, based on Watson and Crick pairing; however, in viruses, DNA and RNA can be either single-stranded or double-stranded.
