A self-assembly abstract molecular model of a 22 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: 22 Thymine (T) (orange): 11 Adenine (A) (blue): 11 Guanine (G) (green): 11 Cytosine (C) (yellow): 11 Side chain: Deoxyribose (red): 44 Phosphate (purple): 44 Stand: Model stand (light brown): 1 Support Rod (grey): 2 Spacers: 23 Cap (white): 1 Approx. dimensions: H44cm x ’Ù11cm
