What happens to the mitotic spindle during mitosis?

By the end of DNA replication, sister chromatids are bound together in an amorphous mass of tangled DNA and protein. Mitotic entry triggers a dramatic reorganization of the duplicated genome, resulting in sister chromatids that are disentangled and separated from one another. Chromosomes also shorten in length, up to 10,000-fold in animal cells, in a process called condensation. Condensation begins in prophase and chromosomes are maximally compacted in… WebMay 19, 2016 · According to the International Nomenclature Committee on Cell Death, the precise definition of mitotic catastrophe is a bona fide intrinsic oncosuppressive mechanism that senses mitotic failure and responds by driving a cell to an irreversible antiproliferative fate of death or senescence [ 3, 4 ]. offline ethereum wallet
