DNA Model

This preassembled, true-to-life DNA model is built to a scale of 10 cm to 1 mm 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 model is supported by a central pillar which can rotate on a circular stand, and the phosphate and deoxyribose components of the backbone as well as the individual base pairs can be removed for separate examination.
Model stands 24 in. tall.
