转载：彻底搞清楚promoter, exon, intron, and UTR

 • 启动子 : RNA 聚合酶特异性识别和结合的 DNA 序列。 • promoter 自然不属于 intron 和 Exon 的任何一个，属于 noncodingsequence 。         • noncoding  RNA 是现在研究的热点之一。我们常见的 MiRNA,SiRNA ,antisense RNA tech, 这些都是属于 ncRNA 的范围。只要你在进一步问下：这些 RNA 是哪里来的？你就知道部分答案，跟那些看似跟编码蛋白没有关系的 DNA 序列有关系。这部分 DNA 有个统称就 junk DNA ，垃圾ＤＮＡ或者冗余 DNA ，他们编码的 RNA 就属于  ncRNA . RNAi 就是迄今最经典的 ncRNA 功能典范。         • An  exon  is asequence of DNA that is expressed (transcribed) into RNA and then often, butwith many noteworthy exceptions[1] , translated into protein. Adjacent  exons  maybe separated by an  intron , which is later removed from the RNAtranscript via the splicing mechanism.  (From Wikipedia)         • UTR （ UntranslatedRegions) 即非翻译区，是信使 RNA （ mRNA ）分子两端的非编码片段。 　         • 5'-UTR 从 mRNA 起点的甲基化鸟嘌呤核苷酸帽延伸至 AUG 起始密码子， 3'-UTR 从编码区末端的终止密码子延伸至多聚 A 尾巴（ Poly-A ）的末端。    转录（Transcription）是遗传信息从DNA到RNA的转移。即以双链DNA中的一条链为模板，以ATP、CTP、GTP和UTP4种核苷三磷酸为原料，在RNA聚合酶催化下合成RNA的过程。 常见问题： 问： Promoter 在 DNA 序列中是算内含子还是外显子？ 答：都不是。 属于 noncoding sequen
