GO
GO:0032784 Any process that modulates the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides catalyzed by a DNA-dependent RNA polymerase. GO:0140673 A chromatin remodeling process that reestablishes the chromatin structure following the passage of RNA polymerase II during transcription elongation, thus preventing cryptic transcription initiation. GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0006354 The extension of an RNA molecule after transcription initiation and promoter clearance at a DNA-dependent RNA polymerase promoter by the addition of ribonucleotides catalyzed by an RNA polymerase. GO:0006353 The completion of transcription: the RNA polymerase pauses, the RNA-DNA hybrid dissociates, followed by the release of the RNA polymerase from its DNA template.
