bart westendorpcancer cells often have abnormal dna content owing to disruption of the pathways that control the cell cycle. cells commit to the cell cycle in response to small peptide signals called mitogens, which ensure entry into s phase, when dna is replicated. once s phase is initiated, the cell cycle is normally self-sustaining and irreversible. however, under certain circumstances, two consecutive rounds
