Simulation of chromatin stretching

Cui and Bustamante [66], Bennink et al. [43], Brower-Toland et al. [42], and Leuba and Zlatanova (unpublished results) have reported single molecule stretching 

While structural transitions at the level of nucleosomes are still outside the scope of current models, applying a constant force to both ends of the liber allows to simulate the low end of the force-extension curve. First results from our own work (Aumann, Caudron, Wedemann, and Langowski, manuscript in preparation) are shown in Fig. 5. In this particular example, a nucleosome repeat of 200 bp and a linker DNA length of 11 bp was used.
