Strawberry dna extraction introduction: dna is found in cells from animals and plants dna is a double stranded macromolecule composed of nucleotide bases pairing 8 slowly pour the ice-cold alcohol into the tube until the tube is half full and forms a layer over the top of the strawberry extract.

I used the alcohol extraction method to isolate dna and to make it visible to the naked eye strawberries have an octoploid genome, which means that the nucleus contains eight complete copies of each chromosome using strawberries in the experiment therefore facilitates the extraction of dna. Dna normally stays dissolved in water, but when salty dna comes in contact with alcohol it becomes undissolved this is called precipitation do only living organisms contain dna try extracting dna from things that you think might not have dna want to conduct more dna extraction experiments.
