Extracting DNA from bananas

The DNA from the banana was white and slimy. For the steps, we had to use the blender to blend the bananas to break up the cell wall. We used soap, water, and salt to break down the cell membrane. We then used ice cold rubbing alcohol was used to separate and show the appearance of the DNA. We retrieved the DNA with a metal rod and examined it. I think the DNA would look different if we used vegetables instead because it wouldn't be so slimy just because bananas are not as solid as vegetables.
