Cells have genes that affect cell division. These genes may be damaged by environmental factors such as radiation, smoking, and viral infections. Oncogenes
stimulate rapid cell division and are normally turned off in adult organisms. Tumor
suppressor genes prevent continuous cell division and are normally turned on in
adult organisms. One of these tumor suppressor genes, called p53, can be turned off
by the effects of smoking tobacco. Based on the above information, what is the most likely result of turning off p53?
A Lungs become black from smoking

B Cells undergo uncontrolled division

C White blood cells are unable to stop infections
