WebApr 23, 2014 · THE CELL. 5. CELL CYCLE A cell cycle is a series of events that a cell passes through from the time until it reproduces its replica. It is the growth and division of single cell into daughter cells and duplication (replication). In prokaryotic cells, the cell cycle occurs via a process termed binary fission. WebCell cycle checkpoints represent an important mechanism through which cells control their progression through the complex processes that ultimately result in cell growth and division. Detailed studies have indicated the role of numerous proteins which function as “stop/go” signals as cells traverse each cell cycle stage.
