[EX Q]: Question: On the molecular biology of cancer: 
 Options:  <0> Oncogenes are mutated derivatives of normal genes, called protooncogenes, whose function is to promote cell proliferation or survival. <1> Oncogenes are genes that synthesize proteins that inhibit cell proliferation. <2> The tumor suppressor genes synthesize proteins that inhibit cell death. <3> Protooncogenes synthesize proteins that promote cell death. <4> Apoptosis is a form of activation of proto-oncogenes.
