1 In which parts of the cheeseburger would you expect to find DNA? Explain your answer. Bun Patty Tomato Lettuce Mayonnaise Sesame Ketchup Cheese Onion J

2 Why do we isolate DNA? (A few examples) Study Genes Identify an organism (a person A pathogenic bacteria / virus) Change, manipulate genes

3 http://Digging into a human DNA (levels of organization)/Digging into a human DNA (levels of organization)

4 DNA extraction from Strawberries: 1.Break the tissue, pressing. 2.Add mixture of soap and salt, mix well 3.Pass through filter to rid of solids. 4.Gently add cold alcohol. 5.DNA shows up in solution!
