Matrix attachment region structure

Model of eukaryotic gene structure and gene expression stages. BEs are boundary elements that bind proteins to prevent the enhancer effects on outside genes. MARs are matrix attachment regions. 

Describe the general organization of a eukaryotic chromosome. What structural role do scaffold associated regions (SARs) or matrix attachment regions (MARs) play Where are genes primarily located relative to chromosome structure ... 

Many DNA molecules are torsionally constrained at their ends, either by being circular, and so lacking ends, or by being attached to a proteinaceous structure, the nuclear matrix. In eukaryotic cells, a region bounded by adjacent matrix attachment sites is a topological domain. 

AADB Algorithmic adaptation of the database to the structure of the controlled territory. A matrix structure is developed with elements reliably attaching environmental elements to geographical coordinates, configuration of the territory of the region, location on it of objects such as airports, and division of the territory into land and water.
