Extracting DNA in Your Kitchen

It is easy to extract DNA from onion cells using equipment and ingredients found in your own kitchen. All you need is:

  • an onion—even a small one contains many hundreds of cells,
  • a blender to break open the cell walls,
  • detergent to break down the nuclear membranes,
  • and salt to allow the DNA strands to clump together.
  • Then add methylated spirits and wait for the DNA to appear!

Continue to find the ingredients and equipment you will need.
