A Taste of Genetics: Build Your Own DNA!
When DNA is taken out of the cell and stretched out, it looks like a twisted ladder. This shape is called a Double Helix. The sides of the DNA ladder are called the backbone and the steps of the ladder are pairs of small chemicals called Bases: Adenine (A) always pairs with Thymine (T), Guanine (G) always pairs with Cytosine (C).
Our 6th Years used coloured jelly tots, liquorice and toothpicks to construct a DNA Double Helix. The liquorice is the backbones; the jelly tots are the bases and the cocktails sticks are the bonds. And the best part of all is that the students got to taste the “DNA” afterwards.
