DNA Extraction 

In to days lesson of science, we did a DNA extraction experiment with kiwi fruit. 

Our aim was to extract the DNA from kiwi fruit. 

Equipment

Spatula, Kiwi fruit, bag, water, salt, cloth, funnel, beaker, dishwashing liquid, ethanol.  

Steps/ Method

1 - Using a spatula, scoop 1/2 Kiwifruit into bad. Add 25ml water + a pinch of salt 

2 - Mush until a thick soup

3 - Pour over cloth into a funnel into beaker

4 - Pour liquid into a test tube. Add dishwashing liquid + swirl. Allow to sit for 5 minutes. 

5 - Tilt test tube on a 45-degree angle and slowly pour 10ml of ethanol down the side.

6 - Allow to sit. 

Here are photos of the DNA extraction experiment results. 

Water helped break kiwi fruit apart.

Salt helped clump the DNA together.

Ethanol helped to see it as it sits on top.

These photos are results. These photos display how it looked over time.  

Here is our final result of the DNA extraction experiment. The clump of the top was the DNA that was extracted from the kiwi.
