Extract the DNA from a Strawberry – Kitchen Science
DNA is the building block of all living creatures, plants and animals. It is found in the cells of animals and determines the genetics or make up of every individual organism. DNA is also present in the whole foods we eat.
Thanks to the special characteristics of strawberries, it is possible to extract, isolate and observe the DNA. You don’t have to be a geneticist. You don’t even need a microscope. All that is needed are some household materials.
The long thick fibers pulled out of the extraction solution are strands of strawberry DNA. DNA is present in every cell of all plants and animals and determines the genetics of the individual organisms.
Steve how do I make this into a science fair project what do I compare it to I cant just extract dna I need something to do with it or something please respond I have 20 days!
Just think of what will happen before you do the project. Then tell the science behind it.
Hi Alejandro – a great science fair project contains variables and tests each one to see which one works the best or doesn’t and then compares the results. To turn this into a science fair project, try changing or switching out one of the materials with something else. Instead of using salt, test baking powder or sugar. Or substitute the dish soap with other materials. Think about it in terms of testing different substances to see if you get the same result.
