THe outer shell of a virus is called the capsid, and consists of various proteins, which are arranged to enable the virus to enter and control a host cell. These proteins are called protomers and are assembled in units called capsomeres.
DNA (Deoxyribose nucleic acid) and it is surrounded by (held in position by) histone proteins forming octamers.
The tin in tin cans rusted rapidly unless protected by a coating. Modern "tin cans" are not made from tin and so they do not have this problem. Now they are made of aluminum.
A virus is not made from cells.
Mainly Diatoms
A coating substance made of shallac, gum, etc.
the protective protein coating
Virus :)

They are covered with a product called Teflon. Teflon is made by Dupont and is a polymer substance that makes cookware non stick and very easy to clean.
A virus has a protective protein coating called the capsid. The capsid is a cover for the genetic material inside, either RNA or DNA.
