Answer:
The amount and arrangement of the proteins and nucleic acid of viruses determine their size and shape. The protein and nucleic acid constituents have properties unique for each class of virus; when assembled, they determine the size and shape of the virus for that specific class. The capsid ensures the virus gets delivered into the host, thereby allowing the virus to continue on. This shows the capsid of the Adenovirus. This capsid is called an icosahedral shape. This is one of the more complex types of capsid.
