The most sensitive structure in a cell for radiotherapy is
-
Cell membrane
-
Mitochondria membrane
-
DNA

Purines and pyrimidines
-
Deoxyribose
-
Ribose
-
Histones
-
Phosphates
Regarding oncogenesis
-
Topoisomerase II causes break in both strands
-
P53 is the most common oncogene mutation causing cancer in humans
-
At G2 − M phase there is loss of inhibitors controlling cell cycle
-
Decrease in telomerase activity causes antitumor effect
