Based on PDB code 1BNA, this is the structure of DNA in its standard (B-form) configuration. DNA, one of the most famous and important molecules in science, stores genetic information by using the 3D shape of four nucleotide bases: adenine, cytosine, guanine and thymine (A,C,G,T). These bases prefer to form pairs, in which A links to T and C links to G. As pairs of AT and CG bases stack together, a beautiful right-handed 3D spiral emerges - the famous DNA double helix.
Our model shows two complete turns of the DNA helix with the two antiparallel strands wound together. The base-pairs are in blue with the sugar-phosphate backbones in grey, orange and red.
Three sizes of the model are available: 125mm, 155mm & 185mm. The 185mm model is 29 million times larger than the 2 nm diameter of the DNA. Each model comes with a removable display stand.
