Damage to DNA and other external factors are evaluated at the G1 checkpoint; if conditions are inadequate, the cell will not be allowed to continue to the S phase of interphase. The G2 checkpoint ensures all of the chromosomes have been replicated and that the replicated DNA is not damaged before cell enters mitosis.
Mitosis, also known as the M phase, is the process of making two identical daughter cells through cytokinesis and nuclear division. Two daughter cells that are diploid are created as a result of cell division and mitosis (M). M phase refers to either mitosis or cell division (also known as cytokinesis), whereas G1, S, and G2 refer to the other three stages.
A stage of cell division is called metaphase (mitosis or meiosis). Typically, each chromosomes is dispersed throughout the cell nucleus. In the process of dividing, a cell's chromosomes compress and travel toward the center while the nucleus disintegrates.
