Then the DNA can be precipitated, or come out of the solution, by adding alcohol. Strawberries are octoploid, which means they have eight copies of the DNA in their genome in every cell! Throughout the entire experiment there were many possible ways that the ending result of the appearance of the DNA could have differed. After the alcohol layer is set up, wait for eight minutes. For instance, the detergent or soap helps to break down the cells outer membrane, and the salt helps to separate the DNA from other materials in the cell.
