所谓转基因动物,就是采用高科技手段将外源基因导入动物体内,与动物本身的染色体融合。这样外源基因能够随着细胞的分裂而增殖,在动物体内生产其所编码的特定蛋白质且遗传给后代。1987年,世界上第一只商业化转基因绵羊在英国罗斯林研究所诞生。经测试,这只转基因母羊的 The so-called transgenic animals, is the use of high-tech means to foreign genes into the animal body, with the animal’s own chromosome fusion. In this way, the exogenous gene can proliferate as the cell divides, producing the specific protein it encodes in an animal and passing it off to the offspring. In 1987, the world’s first commercially-produced genetically modified sheep was born at the Roslyn Institute in England. Tested, this only transgenic ewes
