regulation of transcription by RNA polymerase I mitotic cell cycle phase transition obsolete regulation of transcription from RNA polymerase I promoter during mitotic cell cycle https://github.com/geneontology/go-ontology/issues/14896 true OBSOLETE. A cell cycle process that modulates the frequency, rate or extent of transcription from an RNA polymerase I promoter that occurs during the mitotic cell cycle. regulation of transcription from RNA polymerase I promoter during mitosis The reason for obsoletion is that 'during' should be captured using an annotation extension. biological_process GO:0046017 mitotic regulation of transcription from Pol I promoter regulation of transcription from Pol I promoter during mitosis
