Chromatin: packaging without nucleosomes

Curr Biol. 2012 Dec 18;22(24):R1040-3. doi: 10.1016/j.cub.2012.10.052.

Abstract

Dinoflagellates are unique among eukaryotes in their unusual 'dinokaryons' - nuclei that lack bulk histones. A new study finds that acquisition of a novel dinoflagellate chromatin protein was an early step in the transition to a nucleus lacking detectable nucleosomes.
