Using simple and exclusive components, students easily build their own eight-rung ladder segment of the DNA molecule based on the model proposed by Watson and Crick in 1953. The components are made of color-coded plastic, and are easily assembled and disassembled. The flexible model is twisted to form the double helix structure. The 12 model segments can be attached to each other to make a
giant double helix DNA model that can also be coiled and will be more than 9 ft. long. Includes 50 student worksheets and guides, and detailed teacher’s guide with full background information.
