The Indigo® 36 base pair DNA model is an expanded version of the one appearing on the Big Bang Theory. The latter was built with 2 of our 17 base pair versions while this one has 2 extra base pairs. It stands nearly nearly 2m tall and is as accurate as the original as demonstrated by the fit with the custom Indigo® alpha helix model. Note that the model now comes with a larger, more stable base than is shown in the image.
This "anatomically correct" DNA double helix model shouldn't be confused with poor copies you might encounter elsewhere on-line. Special modifications were needed to make the major & minor grooves as accurate as possible. The difference between the two is subtle but you can see this clearly in a stereo image of the Indigo® Big Bang Theory DNA Model.
I think it looks awesome. Does it only come assembled?

Yes. We only sell the 36 & 17 base pair DNA models assembled. This is to ensure accuracy, especially for the major & minor grooves.
