A self-assembly abstract molecular model of a 12 layer double helix of Deoxyribonucleic acid. Each high quality plastic moulded shape is colour-coded and the number of hydrogen bonds are represented by the pegs forming the base pairs. The approximate scale is 1cm = 2 Angstroms. The model can be displayed as a helix on the stand or unwound into the ladder. Supplied with full instructions.

Base pairs comprising: 12 Thymine (T) (orange): 6 Adenine (A) (blue): 6 Guanine (G) (green): 6 Cytosine (C) (yellow): 6 Side chain: Deoxyribose (red): 24 Phosphate (purple): 24 Stand: Model stand (light brown): 1 Support Rod (grey): 1 Spacers: 11 Cap (white): 1 Approx. dimensions: H24cm x ’Ù11cm
