一系列研究表明,一些小分子RNA操纵着许多细胞功能,它们通过互补序列的结合反作用于DNA,从而关闭或调节基因的表达。RNA是生物体内最重要的物质基础之一,它与DNA和蛋白质一起构成生命的框架。mi-croRNA(mi RNA,即微小RNA)可以通过与特定mRNA结合或调节特定mRNA的蛋白质翻译过程 A series of studies have shown that some small RNAs manipulate many cellular functions, and they turn off or regulate the expression of genes by reacting to the DNA through the binding of complementary sequences. RNA is one of the most important material foundations in the body, and it forms the framework of life with DNA and proteins. mi-croRNAs (miRNAs, ie, microRNAs) can bind to specific mRNAs or modulate the protein translation process of specific mRNAs
