DNA Model - Un-Assembled

This pre-assembled DNA model is built to a scale of 10 cm to 1 nm and accurately depicts a 16 base pair section of DNA. The phosphate-deoxyribose backbone and the four bases are represented by custom plastic moldings that show the shapes of the molecules in scale and illustrate the bonding between them. The handedness of the backbone chains and the relative sizes of the major and minor grooves in the relaxed molecule are correctly portrayed. The model is supported by a central pillar which can rotate on a circular stand. Comes with four DNA Models and a detailed CD and teacher activity manual. Kit large enough for entire classroom. Once your students can work in groups to reassemble the models, teachers can be confident moving on to the next lesson. CD containing lesson plans and teacher guide for our DNA Model. Unassembled models that can be purchased to add to the kit or to build your own kit.
