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.

Features:

  • Pre-built, 24 inches tall
  • 10cm to 1nm scale
  • Attractive color scheme
  • Can be dissembled for closer inspection
  • Central pillar rotates in stand
  • Features a top ring for hanging
  • Very accurate
  • Makes a great desk decoration
  • Excellent for use in a science fair project

Customer Reviews


5 star rating  Exquisite
Bev Sutton from USA, AZ, Tucson
Bought this model for my 8th grade science class. It is an exquisitely detailed scale model that really helps students grasp the structure of DNA

5 star rating  More detailed and accurate than most.
Joshua Abrams from Boston, MA
It has been just what we wanted and kids enjoy studying it. I have seen models where the base pairs are the same size (e.g., A and T both meet in the middle rather than having one having two rings and the other having one).

4 star rating  DNA Model
Ed from Placentia, California, uSA
I had a DNA expert look it over and was told it is a pretty good model. I'm looking forward to helping my grandson, a very bright 7-year-old, work with it. My only disappointment is the total lack of any directions.
