The genes for capsid proteins are

A. part of the viral genetic material
B. part of the host cell genome

C always RNA

D. always DNA

A capsid is the protein shell of a virus, enclosing genetic material. 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.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the answer would be d : p
