The extreme sensitivity of polA(-) cells to thymineless death is due, primarily, to the absence of an extended lag prior to the commencement of death. Once thymineless death has commenced, the rate in polA(-) cells is only slightly faster than in polA(+) cells.
polA(-)细胞对无胸腺死亡的极端敏感性主要是由于在死亡开始之前没有延长的延迟期。一旦无胸腺死亡开始，polA(-)细胞中的速率仅比polA(+)细胞中的速率略快。
