The Cell Cycle
- Mitosis is a stage in the cell cycle when the nucleus divides
- The cell cycle is a series of stages in the life cycle of a cell
- During the growth phase of the cell cycle, the genetic material of the cell (chromosomes) is doubled
- Two copies of each chromosome are produced; these initially remain attached to each other with each strand called a chromatid
- The chromatids will eventually be divided between the two genetically identical daughter cells that form from the dividing cell
- During the growth phase, the number of subcellular structures (such as ribosomes and mitochondria) also increases
