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.
