This is our most basic DNA model but it still shows all the important details including complementary base pairs. It stands 450mm (18") tall & is the original design made by Molymod.
The image has been produced as a stereo pair; click on the image for an enlarged version & then cross your eyes to see it in 3D.
Note that the relative sizes of the major & minor grooves is exaggerated for effect. For more precise models, see our 12 base pair DNA model or our DNA double helix model, 17 base pairs.
