WebFaulty instructions lead to a protein that does not function normally. Each successive cell division will give rise to daughter cells with even more accumulated damage. Eventually, all checkpoints become non-functional, and rapidly reproducing cells that push out healthy cells, resulting in a tumor or leukemia (blood cancer).
