Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

What determines the code, or information, of a DNA molecule?

• the shape (structure) of the nitrogen bases
• the order (sequence) of the nitrogen bases
• the color of the nitrogen bases
