(MARs) also called scaffold attachment regions (SARs), or S/MARs in case of metaphase chromosome as the same sequences appear to attach to the protein substructure in both metaphase and interphase cells.

In interphase nuclei, this underlying proteinaceous structure changes its organization to occupy the entire nucleus; during interphase the structure is referred to as the matrix rather than the scaffold.

The metaphase scaffold consists of a dense network of fibers. Threads of DNA emanate from the scaffold, apparently as loops of average length 30 to 90 kb.
