Q.  What are the viruses and bacteria?
A.  Viruses and bacteria are the smallest living things. Viruses have no cell walls and can only work properly inside the cells of other living organisms. Bacteria are larger than viruses and can exist by themselves.

A virus is made up of a protean coat wrapped around a small amount of DNA or RNA. It can reproduce itself but only when it is inside a living cell. Versus are, there fore, on the borderline between living and non-living things. When they invade cells they usually cause disease.
