normal nucleosome positioning normal nucleosome occupancy at long terminal repeat region 2025-09-26T17:47:32Z vw A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy at long terminal repeat (LTR) regions is normal (i.e. indistinguishable from wild type). Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes.
