part of promoter clearance during DNA-templated transcription RNA polymerase I promoter clearance https://github.com/geneontology/go-ontology/issues/23386 promoter clearance from RNA polymerase I promoter krc 2011-08-15T03:49:28Z A process that mediates the transition from the initiation to the elongation phases of transcription by RNA polymerase I, generally including a conformational change from the initiation conformation to the elongation conformation. Promoter clearance often involves breaking contact with transcription factors involved only in the initiation phase and making contacts with elongation specific factors. biological_process GO:0001182 GO:0001184 promoter clearance from RNA polymerase I promoter for nuclear large rRNA transcript RNA polymerase I promoter escape transcription by RNA polymerase I
