Activity Summary
DNA is found in most living things, and with the right household items DNA can easily be extracted from the cells. Strawberries are a good fruit to use because they are soft, easy to pulverize, and have eight copies of each chromosome in each cell. The strawberry is crushed and the cell membrane is dissolved. Lastly ethanol is used to precipitate the DNA from solution.
