Extracting DNA from fruit
This video shows how to extract DNA from strawberries using everyday items.
Materials:
5 ml washing-up liquid
50 ml water
5 g salt
3-4 strawberries
10 ml vodka (ice cold!)
Spoon
Glass or plastic cup
Plastic bag
Sieve
Kitchen jug
Small cup
Toothpick
Notes:
1) Mixing the washing-up liquid, the water and the salt we create a mixture that will help break up the strawberry cells when we squash them, and release the DNA contained inside of each cell.
2) By passing it all through the sieve we get rid of the solid debris.
3) The vodka is used to pull the DNA out of the mixture. DNA is not soluble in alcohol, so it precipitates out in the white clumps that we can see in the top layer.
** Keep vodka in the freezer, it works best when it is very cold! And gently pour it down the side of the cup.
