Figure 6. Directional correlation functions for model chromatids with varying parameters.

The chain length for all configurations is . Error bars represent the standard error. A. For fixed mean loop concentration we can see that the stiffness increases with the cutoff length . Larger cutoff lengths result in thicker chromosomes and in turn less flexibility. B. Shown are results for and different mean loop concentrations. An increased number of cross-links is associated with a more densly packed chromosome. Thus, the distance between loops is decreased and the repulsive forces between them are stronger. Consequently higher bending rigidities are obtained.
