In this Activity, students extract DNA from liver and onion cells, and precipitate the DNA. The Activity fits well with a discussion of nucleic acids, hydrogen bonding, genetic coding, and heredity. DNA extraction can also be used in conjunction with a discussion of polymers and their properties. This Activity can be used to complement a diffraction experiment illustrating how the double helix structure of DNA was determined.
