DNA Model

Name: Due Date: 2/10/12 Partner: ___

Each student may work by themselves or with a partner to build a DNA model. The model must be in 3-D.

The following are the requirements for the model.
 * 1) the model must be a double helix
 * 2) the model must show at least 8 nitrogen base pairs
 * 3) the model must show a sugar phosphate backbone
 * 4) the model must show that DNA is antiparellel
 * 5) the model must show H-bonds
 * 6) the model must show correct nitrogen base pairing
 * 7) the model must show all 4 nitrogen bases
 * 8) the model must be in 3-D
 * 9) must have labels for all parts

Ways to earn a zero on this model
 * 1) making the model not in 3-D
 * 2) making the model using a kit bought from a store
