染色质分子式:CAS号:性质:是高等生物(真核生物),即DNA在核中与蛋白质、RNA、脂质等形成的复合体基团。这是与细菌等原核生物的DNA不同之处,而这种复合体就是染色质。染色质在核中通常呈分散状态存在,但在核分裂期间则发生凝缩,形成(狭义的)染色体。染色体和染色质是含有DNA的复合体的不同状态。染色质的基本结构是DNA和组蛋白的复合体(核小体),在电子显微镜下可以看到直径10nm的核小体连续成念珠状,念珠具有卷成螺旋状的直径为30nm左右的螺线管结构及直径为400nm的纤维状(超螺线管)等高级结构。人的一个细胞的DNA链可伸展成约90×2cm的长度,在染色质状态下可折叠成1mm长,而对处于分裂期内的染色体,则可折叠成200μm长且可包含在直径小于10μm的核中。使核酸分解酶温和地作用于染色质,可把易受分解部分和不易受分解部分区别开来。易分解部分是RNA合成旺盛的部位,称为活性染色质,不易分解的部分则称为非活性染色质。活性及非活性部分,可因细胞的状态和组织器官种类的不同而发生改变。染色质结构的变化及活性的变动与组蛋白的磷酸化、甲基化等化学修饰以及非组蛋白的解离与结合有关。
