TS =Tumor Suppressor genes
O = Oncogenes
5A. (12pts) Cancer is a genetic disease. Some of the causative mutations are Tumor Suppressor genes, and others convert proto-oncogenes into Oncogenes. In the list of properties below, mark an X in the column for TS, O, or both. TS O both Causes of inherited elevated cancer risk. Leads to uncontrolled cell growth. Typically, spontaneous, gain-of-function mutations. Can cause increased DNA damage. Dominant in...
