Product Description
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 phosphate-deoxyribose backbone and the four bases are represented by custom plastic mouldings 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, and the phosphate and deoxyribose components of the backbone as well as the individual base pairs can be removed for separate examination.
