Strawberry DNA Extraction

You’ve probably heard about DNA on one of those detective shows on TV, but have you ever seen it? DNA stands for deoxyribonucleic acid. Yep. That’s one big word! DNA is special because it holds the code for every cell in your body. Every cell uses DNA as an instruction manual. Our DNA determines such things as what eye colour or hair colour you have. Did you know that even your food has DNA? We are going to take the DNA out of strawberries!

With a strawberry DNA experiment, you’ll extract, isolate, and observe the DNA of a strawberry in a matter of minutes. It sounds impossible, but thanks to special characteristics of strawberries, it’s actually very possible… and simple. You don’t have to be a geneticist. You don’t need a microscope. It’s easy, fun, and all you need are some household materials.

Safety First!
None of the materials we are using today will do major harm. However safety is

always a first priority when it comes to science. Also remember to wash your hands before starting and whenever possible use ingredients in the house to avoid going out.  And last but not least, HAVE FUN!
