DNA has always been a source of fascination for the scientific and unscientific mind alike... after all, DNA is what makes us who are as people; it defines our features, our habits, our traits, the quirks of our personality... Unfortunately for anyone with a curiosity for DNA, there is no feasible method for studying it hands-on without high-priced lab equipment. That's where this handsome DNA Model comes into play.
The pre-assembled 24 inch tall DNA model is built to a scale of 10cm to 1 nanometer 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, and the phosphate and deoxyribose components of the backbone as well as the individual base pairs can be removed for separate examination. All these features make this a most comprehensive and attractive DNA Model; a great gift for aspiring scientists or anyone with an affinity for genetics.
