Kia ora bloggers, in this blog, I will explain the DNA extraction method for a strawberry. You can’t really find it, but DNA is in the nucleus of a cell and is what makes up chromosomes. But DNA is actually a double helix made up of nucleotides, which are made of sugar, phosphates and bases. Humans actually share about 60% if their DNA with strawberries, and from this I’ve learn that DNA looks weird, but extracting it has many uses 3 of which are forensics, geneology and bringing back extinct animals. Still, this one’s a bit further off.
The method for this experiment is.
- Mush ⅓ banana (no skin) in a zip lock bag with a splash of water and a small teaspoon of salt.
- Strain the solution through a cloth into a beaker.
- Add a squirt of dishwashing liquid and stir.
- Pour into a test tube.
- Place the test tube in a beaker filled with WARM water.
- Leave for 10 minutes.
- Slowly pour 5mL of ethanol down the inside of the test tube.
It actually worked, and you could see the DNA but not the individual ones, of course.
