title: Subcloning of the histone DNA sequences of phage lambda Sam 7 h 22 in plasmid pBR 322.
abstract: The histone DNA sequences of the Hind III cluster of the sea urchin Psammechinus miliaris which are carried by the chimeric phage DNA of lambda Sam 7 h 22 have been subcloned in plasmid p BR 322. Due to this procedure single segments of the cluster have been separated from each other and are available as gene specific hybridization probes.
