protein shells are also known as
A
Capsid
B
Nuclei
C
Cell Envelope
D
Chemical Machinery
Explanation: 

Detailed explanation-1: -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-2: -The capsid is also known as the nucleocapsid and surrounds the nucleic acid of a virus. The nucleocapsid includes the nucleic acid and viral protein coat.

Detailed explanation-3: -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-4: -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-5: -Basic virus architecture. Viral capsid proteins protect the fragile genome, composed of nucleic acid, from the harsh environment. The capsid and nucleic acid together are known as the nucleocapsid.
