decreased nucleosome occupancy in euchromatin decreased nucleosome occupancy at highly transcribed RNA polymerase II genes midori decreased nucleosome occupancy at highly transcribed RNA polymerase II genes during mitotic cell cycle 2017-03-15T16:14:10Z decreased nucleosome occupancy at highly transcribed RNA polymerase II genes during vegetative growth FYPO:0005951 A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy is lower than normal in chromatin regions where RNA polymerase II actively transcribes genes. Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes. reduced nucleosome occupancy at highly transcribed RNA polymerase II genes
