Edible DNA Model Project
1. Your challenge is to construct a three dimensional, edible model of
deoxyribonucleic acid. All of the chemical components must be edible; the
bonds connecting the chemicals may be non-edible (i.e. glue). The chemical
components to be included are as follows:
Phosphate groups and Sugar groups (the backbone of the molecule)
Nitrogen bases (base pairs): Adenine, Thymine, Guanine and Cytosine
Each of the nitrogen bases must be the same basic structure, but different in
some way (color maybe?). All of the nitrogen bases must be paired
correctly. Your molecule must be at least 10 base pairs long.
2. Your DNA model must also be accompanied by a key, which identifies each
of the chemical components.
3. Your DNA model must be brought to school along with your completed
student evaluation of the model ( on the back of this sheet) on the following
date:
Monday, March 21 (Red and Green Groups) or
Tuesday, March 22 (Blue and Yellow Groups)
*Note: Two extra credit points will be awarded to any model that can twist and
hang to form a double helix.
*Note: Your model need not be extravagant or expensive. Feel free to make your
model out of simple ingredients found around the house.
