2、的开篇，是本章学习的基础，也是讲课的难点所在，要用2课时。基因是怎样控制生物的性状的？这是本章学习要解决的中心问题。蛋白质是生命活动的表现者，也能够说是履行者，基因对性状的控制，是经过控制蛋白质（包含构造蛋白和功能蛋白）的合成来实现的。本节集中表达的基因指导蛋白质合成的内容，能够说是本章的要点。课程标准中与本节讲课相对应的要求是：概括遗传信息的转录和翻译。“概括”是理解水平的要求，即要修业生能够掌握知识的内在逻辑联系，能够与已有的知识成立联系，进行解释、推测、划分和扩展等。所以，本节讲课不该限制于对转录和翻译过程的纯真描绘，而应当让学生理解转录和翻译的物质构造基础以及两者之间的内在逻辑联系。要

3、达到理解层次的目标，需要指引学生运用已有知识和看法思虑和讨论有关的问题，比方“为何RNA适于作DNA的信使呢？”需要运用有关DNA和RNA构造的知识，以及构造与功能相适应的看法进行分析；“为何是三个碱基编码一个氨基酸呢？”需要学生运用数学知识和方法进行分析。本节教材的特色之一是插图多并且复杂。插图包含构造表示图、化学构成差别图、转录过程流程图、翻译过程流程图和一个mRNA分子上的多个核糖体同时合成多条肽链表示图等。应当在讲课过程中利用好教材上的插图帮助学生理解讲课内容。2一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一
