细胞生命进程经历从生到死多个阶段,涉及基因表达程序在整体机制控制下的一系列协调性改变。遗传信息网络在整体机制中控制基因组表达程序,地位至关重要,是细胞分裂时发生的可遗传性而不涉及DNA链自身序列改变的稳定性分子变化,包括microRNA及其非蛋白编码RNA、DNA The process of cell life goes through many stages from birth to death and involves a series of coordinated changes in the process of gene expression under the overall mechanism control. The importance of genetic information networks in controlling genome expression programs as a whole is the heritable inheritance at cell division without involving molecular changes in the stability of the DNA sequence itself, including microRNAs and their non-protein-encoding RNAs, DNA
