Simple strawberry dna extraction lab
Key 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. Scientists study DNA for many reasons: They can fiStrawberry DNA Extraction is a fun experiment that you can perform using everyday materials. The purpose of this experiment is to develop the interest, knowledge and skills of our students in the areas of biotechnology and life sciences.
Activity 1 - DNA ExtractionWe will extract DNA from fruit to investigate how it looks and feels. This procedure is similar to what scientists have to do before they can use the information contained in this DNA. However, this is not true. Below, we have outlined a simple experiment showing how DNA can be extracted from a strawberry and made visible to the naked eye.

Strawberry DNA ExtractionAll living things have DNA: the chemical instructions on how to make a living thing. It can easily be seen with the naked eye when collected from thousands of cells. 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 smWhat it doesIn order to study DNA, scientists have to extract it from cells.
There are many DNA extraction kits available for scientists to use in the lab, but they all work in roughly the same way. This experiment lets you make your own DNA extraction kit from common household materials. You will extract DNA from strawberries and see the clumps of DNA strands.
