DNA Extraction | Science

Hi everyone! Welcome to another post, the previous week in science we did an experiment where we extracted DNA from kiwifruit. 

Aim: To extract DNA from kiwifruit 

Equipment: Water, test tube, beakers, sand, spatula Ethanol, Kiwifruit, Sandwich bag, bunsen burner, mat, gauze mat, tripod, dishwashing liquid, glass rod, cloth. 

Method:  

1. Cut the kiwifruit in half and skin the kiwi fruit.
2. Squish the skinned kiwifruit with sand and water in a sandwich bag. Then pour through cloth, collect the juice in a beaker, then transfer it into a test tube.
3. Pour water into the beaker and heat up. Put two drops of dishwashing liquid in the test tube with the kiwifruit and rest in the beaker with warm water. 
4. After setting the test tube in the beaker, take it out after 1-2 minutes and add Ethanol. Watch the DNA separate and collect the DNA using a spatula. 

Results: 

Squished Kiwifruit with sand. 

Separated DNA

Kiwifruit DNA

Discussion:

The dishwashing liquid broke the DNA cells of the kiwifruit, then the ethanol separated the DNA.
