MATERIALS

• Blender
• Banana
• Rubbing alcohol,Salt,Water
• Tweezers/toothpick
• Jar & strainer

QUESTION

• What is in the DNA of a banana ?
• What is the best way do extract the DNA?

HYPOTHESES

• I believe the banana DNA will be very string and soggy.
• Since the banana will be blended , that's why I believe that will be the outcome.
• I see the best way would be with tweezers .

PROCEDURE

• Get one banana & cut in small pieces
• Place pieces in blender along with salt and warm water.
• Blend for about 5 - 10 seconds. Strain into jar.
• Add 2 teaspoons of liquid soap & stir mixture.
• Pour rubbing alcohol on the side of jar. 5min. Use tweezers or toothpick to get DNA

RESULTS

• My hypotheses was correct.
• The DNA was very soggy. Much like a slime

CONCLUSION

• I solved my hypotheses
• I would've used more water.
• Finding/extracting DNA is simple.
