Today we did a science lab where we were able to extract DNA from peas. The first thing we did was we blended ½ cup of split peas with one cup of cold water and 1/8 a teaspoon of salt. The reason we blended the peas with the salt water was to break apart the cell wall and separate all of the cells.
If you wanted to you could find the DNA out of a hamburger, however you would not be able to find the DNA in a grain of sugar, salt or anything non-living like rocks and minerals because they don’t have cells.
We learned a lot today and had fun doing it!

After we blended the peas we strained out all of the pulp so that we would only have a really thin pea-cell soup left. Once we strained the soup we added 2 tablespoons of liquid detergent like Dawn dish soap, and let it sit for about five to ten minutes.
