摘要
DNA甲基化是一种主要的表观遗传修饰,是调节基因表达的重要手段。作者在介绍了DNA甲基化机制、DNA甲基化的模式、DNA甲基化特点的基础上,重点论述了DNA甲基化发育分化、X染色体失活、基因组印记和杂种优势等方面的作用。
DNA methylation is a major epigenetic modification of genome and plays crucial role in regulation of gene expres sion. The mechanism, mode and characteristic of DNA methylation were introduced. And the role of DNA methylation in de velopment and differentiation, X chromosome inactivation, gemomic imprinting and heterosis were discussed.
