NEET BIOLOGY

Detailed explanation-1: -Chromophore. Hint: A virus consists of a genetic material core, either DNA or RNA, surrounded by a protective protein layer. Often, an extra spikey coat called the envelope covers this protective coat. Complete step by step answer: A capsid, enclosing the genetic material, is the protein shell of a virus.

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

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: -Capsid-The capsid is the protein shell that encloses the nucleic acid; with its enclosed nucleic acid, it is called the nucleocapsid.
