title: Chromatin directed transcription of 5S and tRNA genes.
abstract: Chromatin prepared by gentle methods from mouse myeloma cells retained its ability to synthesize RNA using bound endogenous RNA polymerase (RNA nucleotidyltransferase; nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6). The transcription resembles that observed in vivo in several respects. The low-molecular-weight RNA species 5S RNA and the 4.5S precursor to 4S RNA, are transcribed accurately and transcription is reinitiated continually in vitro. Their synthesis was not inhibited by alpha-amanitin (1 mug/ml) as was found previously for these species in isolated nuclei.
