Central Dogma: Strawberry DNA Extraction Lab

With the Curriculum Fair resulting in shortened class periods, students worked incredibly efficiently in small groups to extract DNA from strawberries.  We modified the procedure written the day before such that groups of 4 students worked together to prepare 500 mL of extraction solution using one of the 5 available liquid soap products (450 mL water + 50 mL soap + 1 tsp salt).  Each student then extracted DNA from their strawberry and saved an aliquot of the extracted DNA in an Eppendorf tube labeled with the student’s initials which will be used in class tomorrow for further study and analysis.
