Extracting DNA from strawberries is super easy, allowing you to learn about genomics. Join NHGRI Director Eric Green and social media specialist Jenny Montooth as they show you step-by-step how to extract DNA from strawberries using materials available in your kitchen!
Each step in the extraction procedure aids in isolating DNA from other cellular materials. Explain why each step was necessary and put the DNA extraction procedure into context by drawing pictures and writing your responses.
Strawberries have large genomes; they are octoploid, which means they have eight of each type of chromosome in each cell. Thus, strawberries are an exceptional fruit to use in DNA extraction labs and strawberries yield more DNA than any other fruit (i.e. banana, kiwi, etc.).
Deoxyribonucleic acid, or DNA, is the molecule that controls everything that happens in the cell. DNA contains instructions that direct the activities of cells and, ultimately,\ the body. This activity will demonstrate how DNA can be isolated from a strawberry using common household materials.
DNA Extraction from Strawberry. University of California Davis. Partnership for Plant Genomics Education. 2006. Objectives. Students should be able to: Follow a scientific protocol. Describe where DNA can be found. Understand basic chemical nature of DNA. Understand why DNA precipitates with salt/ethanol. Describe appearance of DNA.
Strawberry DNA Extraction Lab - Learn how to extract the DNA (genetic code) from a strawberry using kitchen supplies in this cool biology lab.
Learning Objectives. After completing the lab, the student will be able to: Extract DNA from the cells of strawberry fruit tissue. Activity: Pre-Assessment. In a plant like the strawberry, where would you likely find DNA? Discuss the answers to the questions with a partner (think, pair, share) and then the class.
Objectives. To learn an easy way to extract DNA from a strawberry using household products. To see a large sample of DNA. Background. This DNA extraction activity results in a large quantity of DNA that can be seen with the naked eye.
