RNA absent from cell during vegetative growth altered rRNA or precursor level 20S rRNA precursor absent from cell Consider annotating to a term describing abnormal transcription or abnormal regulation of transcription, but note that changes in RNA levels may result from changes in RNA stability as well as changes in transcription. 20S rRNA precursor absent from cell during mitotic cell cycle 2019-08-19T15:15:11Z midori A cell phenotype observed in the vegetative growth phase of the life cycle in which the amount of 20S rRNA precursor measured in a cell is too low to detect. 20S rRNA precursor absent from cell during vegetative growth undetectable 20S rRNA precursor level during vegetative growth FYPO:0007065 20S rRNA precursor transcripts absent from cell during vegetative growth
