"WebHere we report that FANCM undergoes degradation during mitosis, regulated by β-TRCP and the Polo-like kinase 1 (Plk1). Consistent with reports that FANCM is required for chromatin loading of the FA core complex ( Mosedale et al. 2005 ; Kim et al. 2008 ), we show that the degradation of FANCM controls the dissociation of the FA core complex … " - How is mitosis regulated

WebUnder normal circumstances, cell proliferation is regulated by a number of controllers (positive and negative controllers) that activate and stop cell division. Therefore, in such cases, cells can only divide a given number of times (e.g. replace cells lost during an injury) before they die off or enter growth arrest (the G0 phase). WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...
