This is an accurate space-filling model of the DNA helix (B form) based on position data and using realistic atomic radius ratios between the atoms C, O, H, N and P. It comprises 10 base pairs (sequence: 5'-ATCAAGAACA-3').
The DNA helix was modelled and rendered in Blender 2.77. The simple Cycles materials are included in the .blend file. The .obj file was created using the Blender-internal Wavefront exporter. The material data are stored in the .mtl file.
