Chicken erythrocyte polynucleosomes which are soluble at physiological ionic strength and contain linker histones are highly enriched in beta-globin gene sequences.

abstract：:We have identified and sequenced two members of a chicken middle repetitive DNA sequence family. By reassociation kinetics, members of this family (termed CRl) are estimated to be present in 1500-7000 copies per chicken haploid genome. The first family member sequenced (CRlUla) is located approximately 2 kb upstream f...
