【摘要】 microRNAs(miRNAs)是一类高度保守的、非编码的小分子RNA,通过与靶基因转录的mRNA互补配对在转录后水平调节靶基因的表达。miRNAs对多种生物学过程起必要调控作用。现对microRNAs的合成、作用机制及功能的最新研究进展作一综述。更多还原

【Abstract】 microRNAs(miRNAs) are highly conserved,non-coding RNAs that powerfully regulate geneexpression at the post-transcriptional level.These fascinating molecules play essential roles in many biologicalprocesses.This review tries to have a brief introduction on the progresses on miRNAs study,such as the biosynthesis,processing and the function.更多还原
