abnormal heterochromatin tethering at nuclear periphery increased heterochromatin tethering at nuclear periphery during mitosis 2021-06-03T13:02:44Z increased heterochromatin tethering at nuclear periphery during mitosis during mitotic cell cycle A cellular process phenotype observed in the vegetative growth phase of the life cycle in which heterochromatin tethering at the nuclear periphery persists after the onset of mitosis. Normally, heterochromatic parts of chromosomes, such as centromeres and telomeres, are maintained at the nuclear periphery during interphase and released during mitosis.
