The graphic represents the different stages of the cell cycle. specific genes within the dna, called inhibitors, stop the cell cycle in g1 phase. this process to keep the dna unaltered and the cells dividing at the correct rate. certain chemicals in our environment may result in mutations of cells' dna that in turn prevent the inhibitors from halting the cell cycle. if this happens, may result. a) cancer b) cell death c) color blindness d) birth defects
