title: Polynucleotides associated with histone preparations.
abstract: Histone fractions prepared from various sources by acid extraction or by salt dissociation contained small quantities of ribo- and deoxyribo-nucleotides. These nucleotides were small and heterogeneous and were efficiently removed from histone preparations by ionexchange chromatography. They probably represent contaminants, rather than uniquely complexed nucleotides, of all the histone preparations.
