听说过转基因山羊和转基因兔吗?现在它们已经身价暴涨,成了医药学家的宝贝—用来制药啦。转基因鸡也遇到了这样的好运气:日前,它们获得美国食品和药物管理局批准,加入了转基因动物制药大军。为什么转基因鸡能够制药呢?原来,它们下的蛋中含有一种工程酶,这种酶可用于生产治疗罕见遗传病 Have you heard of genetically modified goats and GM rabbits? Now they have skyrocketed in value and become the treasure of medicinalists - for pharmaceuticals. Transgenic chickens have also encountered such good luck: Recently, they obtained the approval of the United States Food and Drug Administration, joined the army of transgenic animal pharmaceuticals. Why GM chicken can be made? Originally, under their eggs contains an engineering enzyme, this enzyme can be used for the production of rare genetic diseases
