Abstract

Chromatin organization The fundamental level of DNA organization was revealed in 1997 with the determination of the nucleosome core structure. The crystal structure of a tetranucleosome has now been determined at 9Å resolution, showing how nucleosomes are arranged at the next level up, in the chromosomes that are the substrate for DNA replication. The nucleosomes form a two-start helix, and their geometry in the chromatin matrix is best described by the ‘crossed-linker’ model.
