Given graphs P,Q,R and S show four stages of cell cycle i.e., `G_(1)`,S,`G_(2)` and M, but in random order. Identify the stages and match with the activites of the cell.
I. Taxl ol treatment, which prevent microtubule depolymerization, arrests the cell at this tage .
II. With a mitogen treatment , such as an epidemal growth factor, an arrested cell at this stage proceeds to the next stage of the cell cycle.
III. The cell cycle check point at this stage confirms. that DNA duplication is complete before the cell proceeds to the next stage
