Mitosis is needed for growth of multicellular organisms and for repairing damaged tissues within the human body. It is also a method for asexual reproduction for some plants, animals and fungi. It is a continuous process which has 4 division stages. Throughout this article, I will be explaining the steps:
The checkpoints are G1,G2 and the spindle assembly checkpoint
During the interphase, the cell can enter the G0 phase, either temporarily or permanently. The reasons as to why this happen could be due to differentiation (when the cell specializes) or the DNA of the cell may be damaged. These cells enter G0 and an increase in these could lead to diseases such as arthritis or cancer. Some G0 cells can go back into the cell cycle and start dividing again.
This process happens in the matter of seconds in the human body and remains a key process which allows us to function correctly and live the way we do.
