80年代医学上一大突破性进展,即美国科学家们首先应用遗传工程方法人工生物合成的人胰岛素(BHI),1982年通过一系列严格的动物实验和临床试用后,正式批准用于临床。大多数脊椎动物包括人都只有一种胰岛素和一对胰岛素等位基因,人的胰岛素基因位于11号染色体短臂上, A major breakthrough in medicine in the 1980s was the first human insulin (BHI) biochemically synthesized by scientists in the United States. After a series of rigorous animal experiments and clinical trials in 1982, it was officially approved for clinical use. Most vertebrates, including humans, have only one type of insulin and one pair of insulin alleles. The human insulin gene is located on the short arm of chromosome 11,
