论文部分内容阅读
1教材分析1.1教材内容和地位“基因的表达”是现代遗传学的关键内容之一,是“遗传的物质基础”一节的最后一部分,是对DNA的结构和复制知识的具体应用。通过这部分内容的学习,学生就能在生物性状的遗传和变异的复杂现象中,懂得变异的实质及规律。这节课的内容既是前面所学的有关蛋白质基础知识的应用,又是后面学习遗传的基本规律和生物变异的理论基础,所以本节课在知识的学习上起着承上启下的重要作用。
1 textbook analysis 1.1 textbook content and status “gene expression ” is one of the key elements of modern genetics, “genetic material base ” the last part of the section on the structure of DNA and copy specific knowledge application. Through this part of the study, students will be able to understand the nature and pattern of variation in the complex phenomena of inheritance and variation of biological traits. The content of this lesson is not only the application of the basic knowledge of protein, but also the basic rules of inheritance and the theoretical basis of biological variation. So this lesson plays an important role in the study of knowledge.
