“基因工程”是高考考查的热点,主要考查的内容有基因工程所用到的工具、基因工程的操作过程。考查基因工程的基础知识多以选择题的形式出现;考查与基因工程有关的综合知识,常与DNA的结构、复制、基因的表达相联系,多以实验分析和信息材料题的形式出现。在一些理综试卷中,与胚胎工程、克隆技术、组织培养等知识综合考查学生解决实际问题能力的试题所占比重有所增加。一、考点解读考点1基因工程的理论基础1.基因拼接的理论基础 “Genetic Engineering ” is a hot spot for college entrance examination examination, the main test of the contents of the tools used by genetic engineering, genetic engineering process. Examining the basic knowledge of genetic engineering in the form of multiple-choice questions appear; examine and genetic engineering-related comprehensive knowledge, often associated with the DNA structure, replication, gene expression, mostly in the form of experimental analysis and information materials appear. In some science papers, there is an increase in the proportion of questions with students’ ability to solve practical problems related to embryo engineering, cloning techniques and tissue culture. First, the test center interpretation of a theoretical basis for genetic engineering 1 stitching theoretical basis
