Formation and stability of higher order chromatin structures. Contributions of the histone octamer.

Unique roles have been identified for the histone octamer in the formation and stabilization of higher order chromatin structures. Histone octamers were assembled onto 12 tandem repeats of Lytechinus 5 S rDNA, at either saturating or subsaturating ratios. The extent of oligonucleosome folding and intermolecular association in divalent salts was monitored… CONTINUE READING
