Introduction:
In cell cycle, a mother cell divides into two daughter cells. The cell cycle mechanism is divided into four stages such as G1, S, G2, and M. G1, first gap phase within interphase, is also known as growth phase. During the G1 phase, cell synthesizes proteins and produces more number of mitochondria and ribosomes and increases their size of growth. In the G1 phase, cell synthesizes and accumulates materials needed for
