WebApr 15, 2015 · Localized delays of nuclear envelope reassembly require Aurora B kinase activity. In cells with reduced Aurora B activity, there is a decrease in the frequency of local nuclear envelope reassembly delays, resulting in an increase in the frequency of acentric-bearing, lamin-coated micronuclei. These studies reveal a novel role of Aurora B in ... WebA unique feature of of nucleus is that it disassembles and re-forms each time most single divide. At the ab a my, the chromosomes compaction, the nucleolus disappears, and the nuclear envelope breaks down, resulting in an release of most of an contents of the nucleus at the cytoplasmic.
