遗传工程是分子遗传学一个崭新的内容,是指把一种生物细胞中的遗传物质(脱氧核糖核酸,简称 DNA)从细胞中提取出来,在体外进行复制,然后又通过运载体,将这种复制的遗传物质转移到另一种细胞内,从而改变这个细胞的遗传结构,产生新的性状。遗传工程是七十年代初形成和迅速发展起来的。大量的研究成果表明,遗传工程将是人类干预生物,使之符合自己愿望的一种新型有效工具,它具有广阔的前景。就农业生产而言,最重要的无非是优良品种和肥料。在当前用常规育种法育成的品 Genetic Engineering is a brand new content of molecular genetics, refers to the biological cells of genetic material (DNA, referred to as DNA) extracted from the cells, in vitro replication, and then through the carrier, this The copy of the genetic material transferred to another cell, thereby changing the genetic structure of this cell, resulting in new traits. Genetic engineering was formed and rapidly developed in the early 1970s. A large number of research results show that genetic engineering will be a new and effective tool for human intervention in biology to make it fit their own wishes. It has broad prospects. In the case of agricultural production, the most important are nothing more than fine varieties and fertilizers. In the current breeding products with conventional breeding
