Condensation of a single chromatin chain in the Type I model

The movie shows the full length of simulated chromosome condensation. Nucleosomes are shown as grey spheres, condensin binding sites are in red. If more than two condensin binding sites come within 40 nm of each other, they are highlighted by a yellow sphere to indicate ‘rosette’ formation. Chromatin loops that connect condensin binding sites within rosettes are tinted cyan. A balanced co-existence of rosette and web-like structures in the compacted mitotic stage becomes apparent.
