A. A linear relationship between the average distance of monomers from the backbone and the cutoff length is found. Together with the observed drop off of the monomer density at the central axis we conclude that the fibre coils around the backbone in a helical-like folding manner. However this gives just a general tendency and the exact structure is much more complicated. B. Interestingly we can see that at constant values for the lengthwise compaction ratio still increases linearly with the chain length . In this example and the mean loop concentration is . When extrapolating the linear curve to a compaction ratio of -fold, a polymer with statistical segments and cutoff length would be needed.
