Before You Start
TOTAL PROJECT TIME:
DNA, genome, genes, biochemistry, DNA extraction
Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. DNA is so important that it can be found in nearly every cell of a living organism. In this activity, you will make your own DNA extraction kit from household chemicals and use it to extract DNA from strawberries.
