Method:

  1.  Mush half a kiwifruit in a zip lock bag with a splash of water and a small teaspoon of salt.
  2.  Strain the solution through a cloth into a beaker.

Where do you find the DNA?
In every organism, there is a cell and within that cell, there is a nucleus. There are 46 chromosomes in the nucleus and in those chromosomes there are strands of DNA. 

What makes up DNA?
DNA is made up of simple repeating units called nucleotides. A nucleotide is comprised of sugar, a phosphate, and a base. The sides of DNA are made up of sugar and phosphate. These sides are linked together by chemicals called nucleotide bases.
