In this experiment, I had to make a model of a DNA using liquorice, different coloured marshmallows, and toothpicks.  The liquorice represents the double helix. The backbones of the DNA are made up of sugar and phosphate. The different coloured marshmallows in the photo represents the bases which are adenine (yellow marshmallow), thymine (orange marshmallow), guanine (green marshmallow), and cytosine (pink marshmallow). The rungs or base are always bonded in a certain way, adenine (A) double bonds with thymine (T) and cytosine (C) triple bonds with guanine (G). This activity gave me a better understanding of DNA. Matching the bases helped me remember their names, letters, and also their pairings and also gave me a general idea of what DNA looks like.
