normal nucleosome positioning normal nucleosome occupancy at tRNA genes midori A cellular process phenotype observed in the vegetative growth phase of the life cycle in which nucleosome occupancy is normal (i.e. indistinguishable from wild type) at tRNA genes. Nucleosome occupancy measures the tendency for DNA in a given region to be packaged into nucleosomes. 2017-02-07T14:34:49Z normal nucleosome occupancy at tRNA genes during mitotic cell cycle normal nucleosome occupancy in tRNA genes FYPO:0005920 normal nucleosome occupancy at tRNA genes during vegetative growth
