DNA Extraction | Science

Hello everyone! this past week we have learned about DNA and have conducted an experiment, extracting DNA from kiwi fruit.

Aim:

- Our aim was to extract DNA from a Kiwi fruit.

Equipment:

- Water, Beakers, Sand, Spatula, Ethanol, Kiwi Fruit, Sandwich bag, Bunsen Burner, Heat Mat, Gauze Mat, Tripod, Test Tube, Dishwash Liquid, Glass Rod, Cloth.

Method:

Step 1 

( Result )

- Put the peeled kiwi fruit in the sandwich bag, add sand and water and mash it.

Step 2

- Pour the kiwi fruit through the cloth and collect the juice in a beaker.

Step 3

- Put water in a beaker and heat it up until it's warm.

Step 4

- pour the Kiwi fruit juice into a test tube with two drops of dishwashing liquid.

Step 5 

- Put the test tube in the beaker with warm water and let it rest.

Step 6

- pour the ethanol into the test tube and mix gently using a glass rod.

Step 7

- Wait until the DNA separates and collect using a spatula.

Discussion:

- We used a bit of dishwashing liquid with the crushed kiwi fruit to break down the walls and separate the cells of the kiwi fruit from each other. We then poured in the ethanol which separated the DNA from the kiwi fruit.
