 ===Histones===
-His tones are located within the chromosome. The histones are used in order to from nucleosomes. Inside of the nucleosomes are eight histone molecules, 146 base pairs of DNA, and histone (H1) (Purves, 171) in a nucleosome a histone is positively charged and DNA is negatively charged. When the histones and the DNA combine and the histone reduces its charge it will the give off the DNA. Acetylation is used to catalyze the histone to disaggregate the nucleosome (Purves, 294). A histone is any one of a group of basic proteins forming the core of a nucleosome, the structural unit of a eukaryotic chromosome (Purves, G-12).
