Apple vs. Peas

Marie and Jess

Question

How does the amount/appearance of pea DNA compare to red apple DNA?

Hypothesis

I believe that there will be more DNA from an apple than a the peas because the cells are smaller in the apple. Therefore there are more of them. Also peas have thicker cell walls than apple cells.

Materials

  • Blender
  • Soap
  • Alcohol
  • Cups
  • Test tubes
  • Meat tenderizer
  • Pipette
  • Apple
  • Peas
  • Hooks
  • Scoopula
  • Ice
  • Salt
  • Coffee filter

Procedure

  1. Get materials
  2. Blend peas and apple. Make sure to use the same amount of water, salt, and apple
  3. Strain and place in cup
  4. Add a few drops of soap to all cups. Let sit 5 to 10 minutes.
  5. Add enzyme, stir softly, and transfer to test tube. (1/3 full)
  6. Add alcohol slowly
  7. Observe and compare and record. (drawings, observations, and take pictures)

Conclusion

We found out that the apple had more DNA than the peas. The DNA in the apple was clear and it wasn’t floating. The DNA in the peas was white and thick. There was more DNA in the apple than the peas because apples have 34 chromosomes and peas have 14 chromosomes. The more chromosome there, the more DNA there will be in an organism.




Possible Errors:


We could have not measured the same amount of salt, water, soap, meat tenderizer, or the peas or apple. That could have caused the DNA to look different. We could try to eliminate errors by measuring more precisely.
