Kemtec®. For building a scale model (1 cm = 1Å) of the double stranded deoxyribonucleic acid molecule. Students learn the detailed chemical structure and sequence of polynucleotides and observe the basis for polarity within the phosphate-sugar backbone, features relevant to the genetic function of the molecule. Sixteen base pairs provide numerous coding triplet (codon) possibilities. The completed model, in the shape of a double helix about 55 cm H, demonstrates the spatial relationships in DNA revealed by Watson and Crick.

It is held together by a metal shaft on a wooden base. All molecular components are flexible plastic, white in color, with Pop-It Bead connections. With instructions.
