This pre-assembled DNA model is built to a scale of 10cm to 1nm and accurately depicts a 16 base pair section of DNA. The phosphatedeoxyribose 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. Dimensions of the model are 24" high x 8" in diameter, making it suitable for classroom demonstrations
