ZoS 57/20

DNA double helix (Type B-DNA)

Scale: 30 x 10E6 :1, in SOMSO-Plast®. Developed in co-operation with Prof. Dr. H.P. Jennissen, Dr. M. Laub and Prof. Dr. G. Witt. Based on data gained from x-ray diffraction studies, the model shows a section of a DNA double helix. The conformation of this double helix corresponds to the so-called B-DNA, which is physiologically more significant when compared with the respective A or Z form. This is a matter of a clockwise double helix with 10.5 green base pairs per coil and equivalent to a passage height of approx. 3.4 nm. It complies, in the main, with the model of the DNA structure developed by Watson and Crick in 1953. Although the human genome has billions of green base pairs the top or bottom section of the model shows 12 green base pairs, respectively, which means to say 1 coil. In one piece. Mounted on a rotating stand with green base.
