Cells go through a repeating cycle of events in growth regions such as plant root tips and animal embryos. Outline this cell cycle.

This cycle can be split into two big parts: the interphase and the dividing phase. The interphase consists of the G1, S and G2 phase. In the G phases the cell increases in size to prepare for the division and duplicates organelles such as the mitochondria to ensure enough numbers in both the cells that are to be created.  The dividing - or mitotic- phase occurs at the end of the G2 phase, and allowsf or the circle to begin again with a new G1 phase. The mitotic phase is where mitotic division occurs which results to two genetically idetntical daughter nuclei in two identical cells. It consists of four phases - prophase, metaphase, anaphase and telophase- and is folowed by cytokinesis which allows for the splitting of the initial cell into two daughter cells. In order for mitosis to happen, the DNA in the replicating cell needs to be duplicated and that happens in the S phase of the interphase through a process called DNA replication.
