Data Collection of Strawberry DNA Extraction

Record observations here:

Match the procedure with what it is doing to help isolate the DNA from the other materials in the cell:

______Break open the cell                                      A. Squish the fruit to a slush

______Dissolve cell membranes                           ______Dissolve cell membranes                            B. Filter your strawberry extract  through cheesecloth

______Precipitate the DNA                                    ______Precipitate the DNA                                    C. Mix in a detergent solution

______Separate organelles, broken cell                D. Layer cold ethanol over filtered extract 

           wall and membranes from proteins, 

            carbohydrates and DNA

Questions:

Applying your previous knowledge regarding cells, DNA is soluble in water, but not in ethanol.  What does this fact have to do with our method of extraction? 

Explain what happened when the ethanol came in contact with the strawberry extract.
