Steps 1
We manged to see the DNA in this experiment using a simple method.
- Create a banana mixture by adding a peeled banana to 1–2 cups of distilled water in a blender.
- Add 20 ml of distilled water to a disposable cup
- Add one teaspoon of shampoo and a couple pinches of salt to the water
- Add 3 heaping teaspoons of banana mixture to the cup and stir slowly for 5–10 minutes.
- Then place a coffee filter inside a second (empty) cup. Fold the sides of the coffee filter around the edge of the cup so the filter is not touching the bottom of the cup
Steps 2
- slowly pour the mixture from the first cup into the coffee filter
- Allow the mixture to drain for 5–10 minutes until several milliliters of filtrate have passed through the filter into the bottom of the cup. Carefully remove the filter and throw it in the trash.
- Finally use the pipit to transfer the filtrate (liquid at the bottom of the cup) to a test tube of ice cold alcohol.

The SCIENTIFIC PRINCIPLE
To see the DNA that was in all living things, also learned a way we could separate the DNA and see it in a simple way
