Summary

Prokaryotes and Viruses discusses prokaryotes and viruses. Prokaryotes are the smallest living organisms, and viruses, by the definition of "living," are not actually alive. Both can be harmful, but we need bacteria to survive, and the uniqueness of viruses has made them a very useful tool to improve the human condition.
