细胞凋亡是一种不同于细胞坏死的细胞死亡方式，具有特殊的形态学及生物化学特征。其生物化学变化主要表现为内源性核酸内切酶的激活。它依赖于Ｃａ２＋、Ｍｇ２＋的核酸内切酶从核小体间连接处将双链ＤＮＡ切断，形成以１８０ｂｐ为最小单位的ＤＮＡ片断，经琼脂糖电泳分...
Apoptosis is a cell death mode that is different from cell necrosis and has special morphological and biochemical characteristics. Its biochemical changes are mainly manifested by the activation of endogenous endonucleases. It depends on Ca2+, Mg2+ endonucleases to cut double-stranded DNA from the nucleosome junction, forming a DNA fragment with a minimum unit of 180bp, separated by agarose electrophoresis...
