  1. How the Experiment works:

    – When you mash the banana, you are breaking apart the tissues and tearing open the cell walls to expose the inner contents.
    – The dish soap breaks down the fatty layer of cells to spill out the DNA.
    – The salt neutralizes the negative charge of the DNA strands, causing the DNA to stick together like a DNA gathering.
    – The coffee filter traps the large chunks of plant tissue and cell debris while letting the liquid with the DNA pass through.
    – The DNA is not soluble in alcohol, so when you pour the rubbing alcohol, the DNA precipitates and clumps together into visible white cotton-like or stringy fibers.
