WebDepletion of SMC-4/MIX-1 causes aberrant mitotic chromosome structure and segregation, but not dramatic decondensation at metaphase. Moreover, SMC-4/MIX-1 depletion disrupts sister chromatid segregation during meiosis II but not homologous chromosome segregation during meiosis I, although both processes require chromosome condensation.

Web29 okt. 2024 · Metaphase is a third stage in the cell division process (mitosis or meiosis). Individual chromosomes are rarely visible in the nucleus of a cell. The chromosomes condense and become distinct during the metaphase stage of mitosis as they align in the middle of the dividing cell. Web7 apr. 2024 · This approach showed phenomena otherwise impossible to discern in a clinical setting. Starting from PNBD, chromosomes required more than 2 h to achieve full alignment into the metaphase plate and initiate sister chromatid segregation. Afterwards, the interval from anaphase to the start of furrow ingression persisted for ∼45 min.
