Extracting DNA From Fruit




Introduction: Extracting DNA From Fruit

ever wanted to see some DNA. well here you go.

Step 1: What You Need

You need some water, salt,a sieve, a couple strawberries, cups,a meat tenderizer,some rubbing alcohol, test tubes, detergent, Popsicle sticks, and finally, a blender.

Step 2: Blender Time

Put the strawberries ( about 3) a pinch of salt and a cup of water in the blender.blend for 20 seconds .pour the solution through the seive into a cup.

Step 3: More Steps

Estimate about 1\6 of the mixture and add that amout of detergent to the solution. mix it together . let it sit for around ten minutes.

Step 4: Now the Fun Part

pour some of the solution into a test tube until its about half full.now add some rubbing alchohal(the same amount as the strawberry mixture) by pouting it carefully down the side of the glass. The alcohol should sit on top of the solution.suprisingly DNA will rose up from the strawberry solution and into the alcohol in thick strings.Feel free to pick it up with the Popsicle stick. Don't eat it though.
