NEET BIOLOGY

Detailed explanation-1: -A virus is made up of a DNA or RNA genome inside a protein shell called a capsid.

Detailed explanation-2: -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.

Detailed explanation-3: -A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Sometimes the capsid is surrounded by an additional spikey coat called the envelope.

Detailed explanation-4: -When a virus particle is independent from its host, it consists of a viral genome, or genetic material, contained within a protein shell called a capsid.

Detailed explanation-5: -Viral Structure. In the simpler viruses the virion consists of a single molecule of nucleic acid surrounded by a protein coat, the capsid; the capsid and its enclosed nucleic acid together constitute the nucleocapsid.
