近几年的高考试题都从不同角度考查了学生对基因工程专题理解和掌握的情况。现就基因工程的内容进行简单归纳总结。考点1基因工程的诞生基因工程理论依据:(1)DNA是遗传物质;(2)DNA双螺旋结构和中心法则的确立;(3)遗传密码。基因工程技术支持:(1)基因转移载体的发现;(2)工具酶的发现;(3)DNA体外重组的实现;(4)重组DNA表达实验成功;(5)PCR技术的发明。基因之所以能够“嫁接”的原因是不同生物
In recent years, college entrance examination questions from different angles examine the students understand and master the case of genetic engineering. Now on the content of genetic engineering for a simple summary. Test site 1 gene engineering was born Gene engineering theory basis: (1) DNA is genetic material; (2) DNA double helix structure and the establishment of the central rule; (3) genetic code. Genetic engineering and technical support: (1) discovery of gene transfer vectors; (2) discovery of tool enzymes; (3) realization of DNA in vitro recombination; (4) success of recombinant DNA expression experiments; The reason genes are “grafted” is due to different organisms
