Instructions

  • Gather the supplies needed to create edible DNA
    make a DNA model with gummy bears and candy.
  • Separate four colors from the gummy bear candies. Place them into the bowls.
  • Pair two colors together to represent Adenine, Thymine, Cytosine, and Guanine. *Reminder: Adenine and Thymine go together, and Cytosine and Guanine always go together
  • Insert a toothpick through the side of the licorice. Add the first pair of nucleotides A & T, and repeat with another toothpick and a second pair of nucleotides C & G.
