1) If we gave a tumor a single dose of radiation which cells would die (i.e., G1, S, G2M)? If we gave a tumor afractionated dose of radiation which cells would die (i.e., G1, S,G2M)? What would happen to the tumor after the single radiation dose or during fractionation? (i.e., would the tumorcells regrow, synch, redistribute?)

2) Does cell cycle affect OER (oxygen enhancement ratio) ?
