Type: Model
Topic: DNA Structure
Grade Level: Late elementary, middle school, high school, the general public
Contributor: Nancy Hutchison
School: Fred Hutchinson Cancer Research Center, Seattle, WA
Purpose: To demonstrate DNA helical structure, complementary base pairing, and the sugar phosphate backbone in a three-dimensional, schematic way.
Materials: DNA model is made from plastic and wooden dowels that have been painted in bright and appealing colors. The model compresses for easy storage or expands into full double helix form. DNA Model (#45091) can be purchased for $49.95 from Science Kit & Boreal Laboratories (800-828-7777).
Methods: Pass around the DNA model and let students feel it, compress it, expand it, play with it. Kids love this model!
