Science: DNA Extraction Experiment

 In our lesson in Science, we did an experiment about our topic, which was "Genetics and Evolution". Our experiment is about extracting DNA from fruit. 

Equipment: 

• kiwi fruit or strawberry
• beaker
• stirring rod / or a stick
• ziplock bag
• detergent
• salt
• rubbing alcohol
• filtering paper
• water

Method:

1. After peeling the skin, mash the fruit in a ziplock bag until it's squishy and wet. 

2. Filter the mashed fruit in a beaker through a filtering paper until the juices are gone. 

3. Put a pinch of salt and liquid detergent and water with the mashed fruit in a beaker and stir it with a stick or stirring rod. 

4. After stringing the mixture, pour rubbing alcohol on the mixture and try not to move it around too much. 

5. After waiting for a couple of seconds, a slimy like texture will appear, with a stick scoop that slimy liquid out and that's it.
