Core histones are found in the nuclei of eukaryotic cells and in most Archaeal phyla, but not in bacteria. The unicellular algae known as dinoflagellates were previously thought to be the only eukaryotes that completely lack histones, but later studies showed that their DNA still encodes histone genes. Unlike the core histones, homologs of the lysine-rich linker histone (H1) proteins are found in bacteria, otherwise known as nucleoprotein HC1/HC2.
