Viruses are made up of only atoms and molecules; they contain genes in the form of either DNA or RNA. They have no metabolic activity and therefore, cannot maintain a steady internal state. When a virus infects cells, it forces the cell to make more copies of the virus. The genes found in populations of viruses change over time allowing viruses to acquire new characteristics and features. Categorize each characteristic of life into the "YES" or "NO" category depending on whether a virus has it or not.
