Extracting DNA from a tomato

Adrián Oliva Muñoz 4ºB

REQUIRED MATERIALS

  • Liquid soap
  • Salt
  • Ethyl Alcohol
  • Pineapple juice
  • A Tomato
  • A pair of plastic glasses
  • A plastic bag
  • A strainer
  • And a knife

FIRST STEP

First of all, we cut the tomato into pieces and we squash it until it became liquid (inside the bag)

Then, we add a spoon of salt and we close the bag

When everything is mixed, we start to strain the tomato with the aid of a strainer (to one of the glasses)

SECOND STEP

Once the tomato is filtered, we add a spoon of soap to the glass and we wait 7 minutes until the fibres get broken.

THIRD STEP

After the 7 minutes, we add the juice, that help us breaking membranes and extracting DNA. After mixing, we must stir carefully. Once this is mixed, we must add alcohol quite carefully by the sides of the glass (keeping the DNA save, without any strange movements)

FOURTH STEP

Finally, we extract DNA mucoses with the aid of a stick and we put them into a vial filled up with alcohol

And that's all, we have already extracted DNA from a tomato!
