Virus envelope is known as
Virus envelope is known as
Open in App
Solution
The correct option is A Capsid
A capsid is the protein shell of a virus. It consists of several oligomeric 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. The capsid encloses the genetic material of the virus. Thus, option B is correct.
Virion is an entire virus particle, consisting of an outer protein shell called a capsid and an inner core of nucleic acid. Thus, option C is wrong.
Nucleoprotein is a combination of both genetic material and capsid. Thus, option D is wrong.
The "core" of a virus is the nucleic acid (either DNA or RNA) that makes up the viral genome. This core contains all the genetic information of that virus, and is enclosed within the protein coat known as the capsid. Thus, option A is wrong.
