-An easy-to-assemble DNA model, this stunning recreation consists of specially-shaped, brilliantly- colored plastic pieces. Each base in the 12 base pair model is a subtly different shape, and the sugars are made from a slightly difference plastic so the model fixes correctly to create a realistic double helix. You can deconstruct the double helix into two separate strands by moving the central supporting spine and pulling the helix apart along the hydrogen bonds.
