What moves the chromatids during mitosis? Marketing Ch 10

Thu Oct 25 2001 14:30:00 GMT-0400 (Eastern Daylight Time) · During mitosis the chromosomes which have already duplicated condense and attach to spindle fibers that pull one copy of each chromosome to opposite sides of the cell. The result is two genetically identical daughter nuclei. The rest of the cell may then continue to divide by cytokinesis to produce two daughter cells.

The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis. Compare sister chromatids to homologous chromosomes which are the two different copies of a chromosome that diploid organisms (like humans) inherit one from each parent. Sister chromatids are by and large identical (since they carry the same alleles also called …

The spindle checkpoint also known as the metaphase-to-anaphase transition the spindle assembly checkpoint or the mitotic checkpoint is a cell cycle checkpoint during mitosis or meiosis that prevents the separation of the duplicated chromosomes until each chromosome is properly attached to the spindle. To achieve proper segregation the two kinetochores on the sister chromatids must be attached to …

A series of biochemical switches control transitions between and within the various phases of the cell cycle. The cell cycle is a series of complex ordered sequential events that control how a single cell divides into two cells and involves several different phases. The phases include the G1 and G2 phases DNA replication or S phase and the actual process of cell division mitosis or M phase. During the M …

M–Cdk activity promotes the events of early mitosis resulting in the metaphase alignment of sister chromatids on the spindle. M–Cdk activity also promotes the activation of APCCdc20 which triggers anaphase and mitotic exit by stimul…
