Dna Extraction From Cheek Cells Lab Report
Procedure 2: DNA Extraction from Cheek Cells
Materials: Water, Clear Dish Soap, Table Salt, Isopropyl Alcohol (70%) or Ethanol, Food Coloring
1. To 200 Ml drinking water add two teaspoons of salt
2. Gargle the salt water for 1 minute.
3. Spit the gargled water into a beaker (or new cup). Now your cheek cells are suspended in the salt water.
4. Gently stir the salt water with one drop of soap (try to avoid air bubbles)
5. In a separate beaker (or cup), mix 20 ml isopropyl alcohol and 1-3 drops of food coloring
6. Optional: You may want to transfer the gargled salt water/soap solution to a test tube to make it easier to see the DNA.
7. Gently pour the colored alcohol over the top of the gargled water so that it forms a layer on top.
