(tumor suppressor) (inactive tumor suppressor) (oncogene) (proto-oncogene) (oncogene or tumor suppressor) (beats me). E. Suppose you have cells that have permanently active ink protein as in C. The cells also have permanently active E2F or permanently active ras. (Consult texts or handouts for roles of E2F and ras.) E-1. If your cells have active E2F and active ink, then your cells should (grow normally) (fail to grow) grow uncontrollably) (can't predict). E-2.
