Buy the Indigo® 12 Base Pair DNA molecule model which shows the structure discovered by Watson, Crick & Franklin's research, especially the base pair complementarity of the double helix. Read why this is our best DNA Double Helix Teaching Tool.
"Without reservation, I can strongly recommend this particular model building exercise. It requires and reinforces a strong understanding of the details of DNA structure. While it does have a reasonably high level of complexity, it is fun to build and most educational." Dr. Roscoe Stribling, ret'd. Read the full testimonial and why their school bought 10 of them over the years.

After I decided to get a model of DNA, I spent quite a bit of time researching it. I found this one pretty quickly, but kept looking. Finally, I decided to buy it. I am really glad I did. I have studied DNA for some time now, and putting this model together really brought things together in my head. Two dimensional drawings in books became a three dimensional representation right before my eyes. The major/minor grooves and how they are formed became much clearer. This is a cool model. The price is right, too. The less expensive models are fine but don't provide the detail this one does. In my view it was worth spending extra for more detail. Indigo says this is their best teaching model, and I agree. Indigo's service is stellar, too. My order was shipped immediately and arrived in good shape. The directions were fine if in need of some updating. Chris Bingleman helped me a lot-he is a credit to your company. He returned every email I sent, and quickly I might add. I talked with others at the company and was impressed. They care. If you want a really nice DNA model to put on display, this is a good one. I'd do it again.
Thanks for your insights. This model is also unique in having 3 different atom geometries for carbon & nitrogen. It puts that knowledge ofÂ VSEPR theory to good use.
