Mouse leukemic cells (L5178Y) in suspension culture were irradiated and the extent of single-strand breaks and double-strand cuts of DNA was estimated by sucrose gradient centrifugation. The radiation produced 3.0 single-strand breaks per cell (G(1) stage) per rad and approximately 0.3 double-strand breaks per cell (G(1) stage) per rad.
对悬浮培养的小鼠白血病细胞(L5178Y)进行辐射,通过蔗糖梯度离心法估算DNA单链断裂和双链切割的程度。辐射剂量为每拉德时,每个细胞(G1期)产生3.0个单链断裂,每个细胞(G1期)产生约0.3个双链断裂。
