Abstract

Eukaryotes are characterized by the extensive packaging of their genomes, initially in a nucleosomal array, and further into higher order domains. Differential packaging is used as a mechanism of gene regulation, with stable silencing of large domains achieved by packaging the DNA into a heterochromatic structure.
