转基因技术能使生物体接受人们导入的体外基因．造成生物体的性状发生有利于人类的变化。这些基因所决定的性状往往能够遗传，因而在工农业生产。生物育种，以及医疗保健等方面具有非常重要的意义。此项技术，目前不仅已从实验研究阶段进入生产应用阶段，而且正不断向深度和广 Transgenic technology enables organisms to accept in vitro genes introduced by humans. As a result, the traits of living organisms are conducive to human change. The traits determined by these genes can often be inherited and thus produced in agriculture and industry. Biological breeding, as well as health care and so has a very important significance. This technology, not only from the experimental stage of research into the production and application stage, and are continuing to the depth and wide
