Full relaxation of the supercoils requires 1 nick/85 kb, thus identifying the average length of “closed” DNA. This region could comprise a loop or domain similar in nature to those identified in the bacterial genome called as metaphase scaffold.

Radial loops in metaphase chromosomes. In the radial loop model of metaphase chromosome organization, domains of 30 kb to 100 kb emanate from a central protein scaffold that spirals through the axis of each chromosome arm..

Matrix-associated regions (MARs) may be identified by characterizing the DNA retained by the matrix isolated in vivo (left) or by identifying the fragments that can bind to the matrix from which all DNA has been removed (right).
