Elongating RNA Polymerase III Transcription Complex NTP elongating pre-mRNA Pol III transcript plus 1 nucleotide elongating pre-mRNA Pol III transcript RNA Polymerase III Productive Transcription Authored: Geiduschek, E, 2004-03-29 17:50:49 Edited: Gillespie, ME, 0000-00-00 00:00:00 GENE ONTOLOGYGO:0006383 Reactome Database ID Release 43113705 Reactome, http://www.reactome.org ReactomeREACT_2251 The principal cleavage products are dinucleotides, and they are produced in large stoichiometric excess over complete transcripts. Overall productive RNA chain elongation proceeds quite rapidly. This event is inferred from an event in Saccharomyces cerevisiae.
