abnormal nucleosome positioning increased nucleosome occupancy 2021-02-23T16:00:13Z FYPO:0007655 A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy is higher than normal at one or more specific sites. Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes. increased nucleosome occupancy during vegetative growth increased nucleosome occupancy during mitotic cell cycle midori
