The purpose of this experiment is to extract DNA from strawberries. I chose strawberries because they are easy to manipulate and they contain a large genome. 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.

Strawberries also contain pectinase and cellulase enzymes, which aid in the degradation of cell walls. (1) The chromosomes are composed of DNA, and they are located inside the nucleus.DNA is extracted by a four step process: the strawberries are first crushed, which mechanically breaks cell walls, and facilitates degradation by pectinase and cellulase. A detergent solution is then used to dissolve the cell membrane and nuclear membrane, which arKey conceptsDNAGenomeGenesExtractionLaboratory techniquesIntroductionHave you ever wondered how scientists extract DNA from an organism.

Overall, DNA tells an organism how to develop and function, and is so important that this complex compound is found in virtually every one of its cells. Each cell has an entire copy of the same set of instructions, and this set is called the genome.
