DNA Extraction Experiment

Aim: To extract the DNA out of the kiwi fruit.

Method: 

1. Mush half a kiwi fruit in a zip lock bag with a splash of water and a small teaspoon of salt.

2. Strain the solution through a cloth into a beaker.

3. Add a squirt of dishwashing liquid and stir.

4. Pour into a test tube.

5. Place the test tube in a beaker filled with warm water.

6. Leave for 10mins.

7. Slowly pour 5mL of methylated spirits down the inside of the test tube. 

Results: 











Discussion: DNA stands for deoxyribonucleic acid. Chromosomes are made of a molecule that is deoxyribonucleic acid that contains the instructions for a feature of yourself, for example, your hair colour is called a gene. The shape of DNA is almost like a twisted ladder but described as a double helix. DNA is made up of nucleotides in which the structure of a nucleotide is base, sugar and phosphate. We share 60% of our DNA with bananas.


Conclusion: Our experiment worked very well. We had gotten most of the kiwi fruit juices out of the kiwi fruit which made our experiment show more DNA. What I would do differently is to try a whole kiwi fruit to see what happens.
