科学家已经建成一种没有任何机械的新型“制药厂”。1999年2月19日,我国第一头转基因牛在上海“哞哞”坠地,取名为“滔滔”。“滔滔”身上携带着人的血清蛋白基因,它的乳汁中含有人血中的一种蛋白质——血清白蛋白。把这些蛋白质从牛奶中提炼出来,就是治病救人的良药。从这个意义上来说,一头转基因牛就是一座用皮肤、骨骼和乳腺等建造的“制药厂”。 Scientists have built a new “pharmaceutical factory” that does not have any machinery. February 19, 1999, China's first GM cow in Shanghai “哞 哞” fall, named “surging.” Totals carry the human serum protein, which contains serum-albumin, a protein found in human milk. The extraction of these proteins from milk is a cure for the disease. In this sense, a GM cow is a “pharmaceutical factory” built of skin, bone and breast.
