DNA dobbel helix model

(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.
