Web(4) Cancer cells often have unusual numbers of chromosomes or mutations in chromosomes. Aging, exposure to toxins (like components of tobacco tar), mutagens (like ultraviolet light) all cause mutations in genes and cancer; but normal errors in DNA replication can lead transformation of the cell if they occur in a crucial gene. Supersession of the mitotic checkpoints in cancer cells causes runaway damage to the cell's organelles, which are units within the cells that carry out specific functions. During normal mitosis, damaged organelles have a chance to repair and recover between cell divisions, but they don't have this opportunity when … See more When a cell divides, it creates two identical daughter cells that each carry a copy of the original cell's DNA.
