SOMSO Chromosome model
SOMSO Chromosome modelScale 50,000 : 1, made of SOMSO-Plast®. The model as been made in co-operation with Studiendirektor Christian Groß. Model in one piece, on a green base. The model shows a submetacentric (centromer away from the middle) metaphase chromosome. The two chromatides are connected with each other in the region of the centromer. Visible there are also the kineto chords oriented to the outside. The slightly irregular surface of the chromatides is explained by the interaction of the chromatin loops coiled on the inside and the supported or imposed proteins. In its lower arm the right chromatide is shown by means of an appropriate cross section without these proteins. As a result the chromatin is visible in the form of different sized loops (loop domains) of the fundamental 30 mm fibril. At their base the loops are connected with a protein scaffold comprising nonhistones around which they wind spirally. The scaffold runs through the two chromatides in counter direction eac
