Where is DNA found?

• Inside the cells of ALL organisms

• Inside the cells of bacteria

• Inside the cells of animals like humans

Every organism has its own UNIQUE set of DNA, however . . .

• DNA works the same way in all living things

• DNA works differently in animals and plants

• DNA works differently between Prokaryotes and Eukaryotes

• DNA works the same between living and non-living things
