10 Science - DNA Extraction Experiment

 DNA Extraction Experiment


Aim: 

Extracting DNA from a 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 10 mins.

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

Discussion:

Where do you find DNA?

DNA can be found in the nucleus.


What makes up DNA?

DNA is made of nucleotides, made in three parts;  a phosphate group, a sugar group and one of four types of nitrogen bases.


Conclusion:

Experiment did work because the kiwi fruit DNA separated from the kiwi fruit. I wouldn’t do anything different because the experiment worked.
