摘要RNA 是所有生物体和生物细胞完成遗传和更新使命的不可或缺的物质,生物学界和医学界也在一直不断的探究,由于 RNA 是细胞内蛋白质合成的中间物质,那么就可以以这个为切入点,通过抑制 RNA 的转录或者与它有关的一些酶的活性,可以达到治疗某些疾病的目的。通过对 RNA 的结构、功能、分类、讨论历史及进展,近而讨论 RNA 在蛋白质合成过程中的具体作用,包括从遗传物质 DNA 到 RNA 的转录过程,以及 RNA 翻译为蛋白质的过程。最重要的是 RNA 干扰技术的应用,通过使某些特定的基因沉默,从而达到抑制蛋白质合成的目的。关键词 RNA DNA 转录 蛋白质的翻译The Structure and Function of RNAAbstractRNA is the indispensable material of all living organisms and biological cells to complete the genetic and update mission,biologists and the medical profession also has comtinued to explore , RNA is protein synthesis intermediates , then you can ues this as a cutpoint , through the inhibition of RNA transcription or enzyme activity it can achieve the purpose of treatment of certain diseases . By RNA structure , function ,classification and study of history and progress of the past studies of the specific role of RNA in the protein synthesis, including the process from the genetic material from DNA to RNA transcription ,and translation from RNA to protein .The most important is the application of RNA interference technolog ,by making certain specific gene silencing ,thereby inhebiting protein synthesis . Keywords : RNA DNA transcription Protein translation目录前言的简要概述1.1 RNA 的概念…………………………………………………………………………………… (1)1.2 RNA 的分类及其作用…………………………………………………………………… (1)1.2.1 信使 RNA(mRNA)…………………………………………………………………(1)1.2.2 核糖体 RNA(rRNA)………………………………………………………………(1)1.2.3 转运 RNA(tRNA)………………………………………………………………...
