title: The 5' ends of bacterial RNA. II. The triphosphate-terminated ends of primary gene transcripts.
abstract: Bacterial RNA, Pulse labeled with 32Pi, was digested with pancreatic RNAase. Oligonucleotides containing a triphosphate group at the 5'-hydroxyl, and therefore derived from the original beginning ends of the RNA transcripts, were purified by hydroxyapatite chromatography and analyzed by two-dimensional paper electrophoresis. A broad diversity of species was found, although the distribution among these species was not completely uniform. Possible methods of utilizing these methods in combination with in vitro synthetic techniques are discussed.
