mitotic arrest in vitro. Accumulating evidence in the research field of radiation biology has demonstrated that the radiosensitivity of cells depends on the phases of the cell cycle; cells are relatively radioresistant in the late S-phase, but are radiosensitive in the mitotic phase (M-phase...
Microtubules, long polymers of tubulin, are critical in the cell's cytoskeleton and play a key role in mitosis. Where is the mitotic spindle? The mitotic spindle is formed from centrioles during the prophase phase of mitosis and is located within the dividing cell, surrounding the dividing ...

A prolonged S phase or mitosis can result in centrosome overduplication. β-Trcp1−/− MEFs show a delay in progressing through mitosis but not through the G1-S transition. Thus, the centrosomal overduplication of mutant cells could be attributable to the mitotic defect. Significantly, the ...
Mitosis is a distinctive cell cycle phase primarily characterized by specific states of chromosome condensation and the formation of the mitotic spindle (mitotic apparatus), a highly complex machinery responsible for chromosome movement, separation of the chromatids, their translocation to the spindle pole...
This is metaphase. Notice the mitotic spindles at either side of the cell. Also, we can see how the chromosomes line up along the metaphase plate or equator The spindles then help tug on the kinetochores which shorten in response to the next phase of mitosis, where the chromosomes begin...

Hence, it is the balance between Aurora B and PP2A-B56 that determines how much RepoMan is chromosome-associated during (pro)meta- phase. This is probably a highly dynamic process because Cdk1 also stimulates the recruitment of Aurora B to the centromeres (Supplementary Fig. 1), which ...
in subsequent divisions, the cellular events leading up to the first post-activation division take a relatively long time. Within this first cell cycle after activation, cells spend a majority of time in the G1 phase, prior to shorter times in the S phase, G2 phase, and then mitosis, ...
at prophase, metaphase, anaphase and telophase was estimated from 100 cells in each of 10 root tip squashes in each species. The percentage of cells, that is from prophase to telophase x the duration of the total cycle in each species gives the duration of the division phase. The duration...
