This is a rough and ready method that should give reasonable quantities of DNA from quite large quantities of material.Lesson organisationYou can run this as a demonstration, or as small group work. Or you could prepare enough of each of several materials to allow groups to take samples from which they extract the DNA.Apparatus and Chemicals.

Extracting DNA from cellsIt is possible to extract DNA from cells in a variety of ways. One of the simplest methods is using peas, soya beans, cress or sweetcorn. Salt water is mixed with detergent and the mashed up substance being tested. The next stage in the method is to filter the mixture and to pour iced ethanol on to the filtrate. Since DNA is the blueprint for life, everything living contains DNA.For this experiment, we like to use green split peas.

Pour your thin pea-cell soup through a strainer into another container (like a measuring cup).Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix.Let the mixture sit for 5-10 minutes.Pour the mixture into test tubes or other smKey conceptsDNAGenomeGenesExtractionLaboratory techniquesIntroductionHave you ever wondered how scientists extract DNA from an organism.

DNA is regularly mentioned in the news and isoften featured in TV detective or crime-scene investigation dramas. DNA, alsoknown as DeoxyriboNucleic Acid, is a long molecule that holds the geneticinformation for all living beings, be it vegetable, animal or a simplemicroorganisms. It is capable of copying itself and can synthesize RNA (RiboNucleicAcid).
