第一节 转录 Transcription 第二节 转译 translation 第三节 遗传密码 The Genetic Code 第四节 遗传密码的破译 Cracking the code 第五节 真核生物RNA

DNA是储存遗传信息的物质,亲代的遗传信息如何真实地传给子代,这个问题的实质就 是DNA分子如何复制(replication)成完全相同的两个拷贝,即DNA的合成,可见通过复 制,遗传信息得以在传代中保留。 DNA分子中的遗传信息又如何表达呢?现知基因表达的第一步是通过转录 (transcription),即DNA的碱基按互补配对(g-c,a-t,a-u)的原则转变为RNA分子上相 应的碱基序列,接着RNA通过翻译(translation),以三个碱基的序列作为一个氨基酸的遗 传密码,从而决定蛋白质的一级结构
