Cancer and the Cell Cycle Cancer is the result of uncontrolled c____ d_______ and can be caused by a m______ in either the proto-oncogene or tumour suppressor gene. Cancer treatments disrupt the cell cycle. E.g. c_________ prevents the synthesis of enzymes needed for DNA replication in the G1 phase. R_______ damages the DNA and causes apoptosis (cell death).

Cancer and the Cell Cycle Cancer is the result of uncontrolled cell division and can be caused by a mutation in either the proto-oncogenes or tumour suppressor genes. Cancer treatments disrupt the cell cycle. E.g. chemotherapy prevents the synthesis of enzymes needed for DNA replication in the G1 phase. Radiation damages the DNA and causes apoptosis (cell death).
