Stesha Britman September 26, 2007 Biology Lab DNA Separation from Strawberries Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms . It is a double stranded macromolecule made up of nucleotide bases coupling Adenine with Thymine and Guanine with Cytosine. I think DNA is capable of being pulled out from cells via an easy method with household chemicals, allowing students to observe strands of DNA with the naked eye. Methods: First my lab partner and I placed 3 ripe strawberries into a Ziploc bag and sealed it shut. The green sepals were removed. Next we pressed the bag for a few minutes to completely squash the fruit. There was lots of fluid when we were done. Then we added 10 milliliters of a DNA Extraction Buffer made of 100 milliliters of shampoo, 15 grams of sodium chloride, and one liter of water. Continually squishing it for a few more minutes. Then we filtered the contents in the bag through a coffee filter set in a 50
