Zos 57/20
DNA double helix
(Type B-DNA), Scale: 30x106:1, made in SOMSO-Plast®
Developed in co-operation with Prof. Dr. H.P.
Jennissen, Dr. M. Laub and Prof. Dr. G. Witt. Model in one piece, supplied on a rotating stand.
Based on data gained from x-ray diffraction studies, the model shows a section of a DNA double helix. The configuration of this double helix conforms with B-DNA, which is physiologically more significant when compared with the respective A or Z form. It is a clockwise double helix with 10.5 base pairs per coil and equivalent to a passage height of approx. 3.4 nm. It complies, in the main, with the model of DNA structure developed by Watson and Crick in 1953.
Height 41,5 cm, width 18 cm, depth 18 cm, weight 0,953 kg
