Build Your Own Candy DNA
When isolated from a cell and stretched out, DNA 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 (also called
rungs) of the ladder are pairs of small chemicals called bases. There
are four types of chemical bases in DNA: Adenine (A), Cytosine (C),
Guanine (G), and Thymine (T). They form pairs in very specifi c ways:
Adenine (A) always pairs with Thymine (T) and Cytosine (C) always
pairs with Guanine (G).
Your task is to use the following materials and procedure to construct
an edible model of DNA. When you are fi nished, use toothpicks
and tape to label one of each of the chemical bases.
