Aurora B is a component of chromosomal passenger complex (CPC), which consists of kinase and three nonenzymatic subunits, that is, INCENP, survivin, and borealin, which regulate the localization, enzymatic activity, and stability, respectively, of Aurora B kinase18. In early mitosis, many ...
The pairs of chromatids then separate, each strand of a pair moving to an opposite end of the cell. When a new membrane forms around each of the two groups of chromosomes, division of the nucleus is complete. The four main phases of mitosis are prophase, metaphase, anaphase, and ...

Cytokinesis is the final stage of mitosis leading to the physical separation of the two daughter cells. In many eukaryotic organisms, such as fungi and animals, cytokinesis is driven by a contractile actomyosin ring (CAR) at the site of cell division. CAR constriction during cytokinesis drives ...

The Cell Cycle Mitosis & Cytokinesis How do cells know when to quit dividing? Cell growth is CAREFULLY controlled. Only certain cells are allowed to divide rapidly. Ex. Hair follicles & stomach lining. One experiment using cells in a petri dish showed that they stopped dividing when they touch...
Meiosis is similar to mitosis in many ways, but there are a couple of important differences. First of all, even though meiosis starts with a diploid cell (a primary oocyte or primary spermatocyte), its end products are 4 haploid daughter cells, each with 23 chromosomes. Instead of being ...

Mitosis relies on forces generated in the spindle, a micro-machine composed of microtubules and associated proteins. Forces are required for the congression of chromosomes to the metaphase plate and their separation in anaphase. However, besides forces, torques may exist in the spindle, yet they ...
