Similarly, you may ask, what fruit is best for DNA extraction?
Experiment to purify DNA from fruit
Bananas, kiwis and strawberries all work well. (Remove the skin of the bananas and kiwi, we just want the insides!) Step 2: In a separate bowl, mix the washing up liquid, salt and tap water. Stir gently trying to avoid making too many bubbles in the mixture.
Subsequently, question is, why is mashed fruit used in DNA extraction? These fruits were chosen because they are triploid (bananas) and octoploid (strawberries). This means that they have a lot of DNA inside of their cells, which means that there is a lot for us to extract. The purpose of the mashing was to break down the cell walls.
Similarly, you may ask, why does a banana have more DNA than a strawberry?
We specifically use fruits like strawberries and bananas because they are octoploid and triploid, respectively. This means that each strawberry cell has eight sets of DNA, and each banana cell has three sets, so there is a lot available for extraction.
How do you extract DNA from a banana?
- Step 1: Chop up the banana. Place the banana onto a plate.
- Step 2: Put the banana into a bag. Place the banana pieces into a sealable plastic bag.
- Squash the banana.
- Step 4: Add salt to warm water.
- Step 5: Add washing up liquid.
- Step 6: Pour into the bag.
- Step 7: Sieve.
- Step 8: Pour the drained liquid into a glass.
