Extracting Kiwifruit DNA

Today in Science, we studied how to extract DNA from a living cell.

We crushed a section of kiwifruit in a mortar and pestle, before adding salt and water. We mixed it in a plastic bag, before filtering it through a cloth and adding dishwashing liquid and putting the mixture in a test tube. We warmed some water in a large beaker before warming the mixture in the water bath. Once it was warm, we added cold ethanol. Our mixture didn't quite work, we suspect it was because we didn't add enough salt.

Heating the mixure

The final product (Not ours!)
