Introduction:
A cell cycle is an essential process by which cells increase in number, while maintaining their genetic stability. In an organism, it is vital for growth and regeneration. However, it has to be tightly regulated to avoid dire consequences. Unregulated, repetitive cell division may lead to cancers which may prove detrimental to the organism. On the other hand, infrequent divisions may end in inadequate growth and regeneration. So, the regulation of cell cycles is paramount for the organism’s survival. Cell cycle checkpoints regulate each stage in the process of the cell cycle.
