Recipe For Extracting DNA

Yes, really! We did this at Context, and Next-Door Grandson and I did it here in my kitchen, so it really really works.

We used:

2 small, clear, capped containers2 tablespoon warm water1 teaspoon raw wheat germ1 squirt liquid hand soap1 teaspoon baking soda1 teaspoon meat tenderizer1 tablespoon rubbing alcoholPut water into one of the clear containers.Add the wheat germ. Stir it to make sure all the wheat germ is wet.Add 1 squirt of liquid hand soap. This destroys cell membranes and releases DNA.Either cap the container and invert gently about 45 times OR don’t cap and stir gently to mix.Add baking soda. This releases the DNA from proteins.Add meat tenderizer. This removes the protein and destroys enzymes that would ruin the DNA.Either cap the container and invert gently 30 times OR don’t cap and stir gently.Let sit for 3 minutes so wheat germ solids settle to the bottom.Pour off the liquid into the second container, leaving the solids behind.Slowly add about 1 tablespoon of rubbing alcohol to the liquid.Wait. Cloudy, stringy stuff will rise to the top. DNA!!

Is that cool, or what?

Look! DNA!!

Go thou and do likewise.

A WRITING PROMPT FOR YOU: Think of three things to do with a bag of wheat germ less one teaspoonful. You may include extracting more DNA as one.
