WebA checkpoint is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle can be halted until conditions are favorable. These checkpoints occur near the end of G 1, at the G 2 /M transition, and during metaphase (Figure 1). Figure 1. The cell cycle is controlled at three checkpoints. WebMitosis refers to a type of cell division (cell cycle) through which the cell (parent cell) produces two identical daughter cells. Unlike meiosis, which is also a type of cell division, mitosis results in the production of two diploid daughter cells. The two daughter cells contain the same number of chromosomes as the parent cell.

WebEukaryotic Cell Cycle and Mitosis. The cell cycle is an orderly sequence of events used by biological systems to coordinate cell division. In eukaryotes, cell division proceeds via a cell cycle that includes multiple spatially and temporally coordinated events. These include a long preparatory/growth period, called interphase, and a mitotic ... WebSenescent cells secrete numerous biologically active factors; the specific secretion phenotype by senescent cell contributes to physiological and pathological consequences in organisms. The purpose of this article is to review the molecular basis of cell-cycle arrest and the senescent-associated secretory phenotype within these cells ...
