WebThese core cell cycle regulators can cause key events, such as DNA replication or chromosome separation, to take place. They also make sure that cell cycle events take place in the right order and that one phase (such as G _1 1) triggers the onset of the next phase (such as S). WebCell growth refers to an increase in the total mass of a cell in terms of cytoplasmic increase. Cell growth and DNA replication are two important processes that take place during cell division, and the sequence of events from the duplication of a cell genome to its division into two daughter cells is termed the cell cycle.
