一、概念介绍基因是生物体遗传信息的载体,它操纵和调控一切生命的遗传性状,“种瓜得瓜,种豆得豆。”转基因技术是指利用分子生物学技术,将某些生物的基因转移到其它物种中,改造生物的遗传物质,使该生物获得新功能。基因片段的来源可以是提取特定生物体基因组中所需要的目的基因,也可以是人工合成指定序列的DNA片段。使遗传物质得到改造的生物,在性状、营养和品质等方面向人类需要的目标转变。通俗地说就是人为将一种生物的一个或几个已知功能基因转移
First, the concept of introduction Gene is the carrier of genetic information of organisms, it manipulates and control all the genetic traits of life, "Transplantation is the use of molecular biology techniques, some Biological genes transferred to other species, transformation of biological genetic material, so that the organism to obtain new functions. The source of the gene fragment may be a desired gene in the genome of a specific organism, or a DNA fragment in which a given sequence is artificially synthesized. Creatures that transform genetic material shift toward what humankind needs in terms of traits, nutrition, and quality. Generally speaking, it is the artificial transfer of one or several known function genes of a living organism
