DNA Model Project
Due Friday January 18, 2013
Your assignment is to build a 3-D model of a DNA double helix. The model should be
large and sturdy and made of non-perishable materials. (Styrofoam, clay, dried pasta,
pipecleaners, candy, beads, etc.)
The model must accurately and clearly show the following:
Double helix structure
Sugar phosphate backbone
Nitrogenous bases are correctly bonding
The following is the DNA code for one strand of your DNA:
TAGGATTACA
Complete the complementary strand and this is the base-pairs you will use on your DNA
model.
Support your model on some kind of sturdy stand, thick Styrofoam board, or give it the
ability to hang from the ceiling. Provide a key with your model showing what each part
of your model represents (example: small red foam balls = phosphates, green
pipecleaners = cytosine, etc…)
Grading (40 pts)
o Components all present; including the key (8 pts)
o Components in proper locations/ relationships (8 pts)
o Components easily recognized or distinguished (4 pts)
o Correct DNA code and complimentary base pairs (4 pts)
o Double helix shape (4 pts)
o Model large enough to see base-pairs and on a support stand (or hang-able) (4 pts)
o Creativity and effort (8 pts)
