DNA, RNA, and Protein Synthesis

Why is DNA important?

• it is very small and very complicated

• it's in everything

• it serves as the blueprint (instructions or recipe) for the traits of all living things

• because we eat it every day for energy

How does RNA differ from DNA?

• RNA contains uracil and deoxyribose
