The position effect is caused by one form of this substance spreading, and scaffolding proteins help this substance form a higher-order structure from a 30nm fiber.
The regular structure of this substance is maintained through the use of repelling elements called container sites. The superstructure of this substance is assayed by the 4C and Hi-C techniques. The SWI complexes serve to restructure this substance via SANT and SLIDE domains. ATPases that alter its structure include INO80 and NURD, which are known as remodeling complexes. CTCF-binding insulators serve as boundary elements in this substance and serve to direct the action of (*) enhancers. The position effect is caused by one form of this substance spreading, and scaffolding proteins help this substance form a higher-order structure from a 30nm fiber. Coming in a lightly staining "eu" and darkly-staining "hetero" variety, this substance appears as "beads-on-a-string" at the smallest scales, and it consists of histone octamers with DNA wound around them. For 10 points name this long stringy substance that condenses into chromosomes, a nuclear complex of DNA and protein.
The regular structure of this substance is maintained through the use of repelling elements called container sites.
