Edible DNA Model


  1. What is DNA. Describe it’s structure.

DNA is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life.

2. Explain what each of the following model pieces represents: licorice, marshmallows( green, yellow, pink, orange), toothpicks.

Licorice: Sugar and phosphate.

Marshmallows: Adenine (yellow), thymine(orange), cytosine(green), and guanine(pink). Yellow marshmallows were pair with orange marshmallows and green marshmallows pair with pink marshmallows. That meant adenine pair with thymine and cytosine pair with guanine.

Toothpicks: Steps of the ladder which are the paired nitrogen bases.

3. Yes. Because this model is looks like DNA, it helps me to learn DNA’s structure.
