The Cell Cycle
The cell cycle is the process of cell growth and division.
It starts when a cell has been produced by cell division and ends with the cell dividing to produce 2 identical cells.
It consists of a period of cell growth and DNA replication, called interphase... and a period of cell division, called mitosis.
Interphase (cell growth) is subdivided into three separate growth stages. These are called G1, S and G2.
G1 - Gap phases 1: cell grows and new organelles and proteins are made.
S - synthesis: cell replicates its DNA, ready to divide by mitosis
G2 - Gap phases 2: cell keeps growing and proteins needed for cell division are made.
These three components make up interphase.
