decreased nucleosome occupancy decreased nucleosome occupancy at 5S rRNA genes decreased nucleosome occupancy at 5S rRNA genes during mitotic cell cycle decreased nucleosome occupancy in 5S rRNA genes A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy is lower than normal at the portion of ribosomal DNA encoding 5S rRNA. Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes.
