Science: DNA Extraction

 Today in Science we did an experiment on DNA Extraction, where we extracted DNA from a Kiwifruit. 

Aim: To extract DNA from a Kiwifruit.

Equipment: Water, test tube, beakers, spatula ethanol, kiwifruit, ziplock bag, cloth. 

Method: 

1. Cut the kiwifruit in half and scoop out the kiwifruit in a ziplock bag.

2. Crush the kiwifruit inside the ziplock bag until chunks are gone. 

3. Add 2 pinch of salt and a little bit of water to the mixture and mix it together.

4. Then pour through cloth, collect the juice in a beaker, then transfer it into a test tube.

5. After pouring the mixture into the test tube, add Ethanol. Watch the DNA separate and collect the DNA using a spatula.

Results:

As a result, there were two layers in the test tube. At the top is the foggy looking texture which is the DNA and the bottom is just the neutral mixture that was from the start of the process. The dishwashing liquid broke the DNA cells of the kiwifruit, then the ethanol separated the DNA.    

Conclusion:

Altogether the experiment was pretty interesting to do and I enjoyed the process. Next time if I got to do this experiment again, I would like to try it on a strawberry.
