Answer 2

A
The structures of viral capsids, the protein coats that protect viral DNA or RNA, have long been studied as paradigms for how proteins interact with each other. While icosahedral virus capsids represent some of the largest complexes for which structures have been determined to date, they are also some of the simplest, often consisting of just one polypeptide building block used multiple times in constructing the capsid shell. Frequently the capsid functions as a vehicle to deliver the viral genome to its destination in the host cell.
