Nucleosomes inhibit both transcriptional initiation and elongation by RNA polymerase III in vitro

To examine the effect of nucleosomes on in vitro transcription, purified chicken erythrocyte core histones and plasmid DNA bearing the Xenopus 5S RNA gene were assembled into nucleosomes and used as templates for transcription in a Xenopus oocyte nuclear extract. Plasmids having a nucleosome incorpo...
