title: Metabolically stable ribonucleoproteins in the chromatin of pigeon bone marrow cells.
abstract: Ribonucleoproteins with buoyant density 1.4 carrying metabolically stable RNA species with sedimentation coefficients up to 28S have been detected in the 0.35M NaCl extracts from pigeon bone marrow chromatin. It is suggested that they correspond to the slowly metabolizing interchromatin particles.
