什么是干扰小RNA? mirnA(微小RNA): MicroRNAs (miRNAs)即微小RNA是在所有真核类中发 的平均长度为22nt的小分子RNA. mi rnas产生于 mRNA pre-mRNA),可与靶mRNA配对并抑制mRNA的翻译 或促使其降解,具有转录后调控基因表达的功能人 类基因组中约有1000种mRNA,可影响60%的基因的表 达与调控 SiRNA(小RNA): mall interfering RNA (siRNA), sometimes known as short interfering rna or silencing rna, is a class of double-stranded RNA molecules, 20-25 nucleotides in length, that play a variety of roles in biology. Most notably, sirNa is involved in the rna interference(RNAi) pathway, where it interferes with the expression of a specific gene.
