共用题干第一篇Genetic EngineeringGenetic engineering began when the DNA molecule（分子）,the most basic unit of life , was first described in 1953 by James Watson and Francis Crick.An understanding of DNA led to the altering of normal cell reproduction.Experiments with altering human cells began in 1970.In one of the first experiments,patients were injected with a virus that would produce a life-saving enzyme,but their bodies would not accept it.In 1980 patients with a rare but fatal blood disease were injected with a purified gene that was cloned through DNA technology.Another failure.Genetic engineering got a legal boost（激励）in 1980. The U. S. Supreme Court said that a patent couldbe granted on a genetically engineered "oil-eating" bacterium（细菌）.This bacterium would help clean up oil spills.The ruling encouraged companies to invent new life forms,and three important medical products were quickly developed.1.Human interferon（干扰素）—a possible solution to some cancers and viral diseases.A newly engineered bacterium produced human interferon as a by-product. This new product reduced the cost of interferon.2. Human growth hormone（荷尔蒙）一for children whose bodies do not grow to normal height. An expensive growth hormone was previously produced from human cadavers,but by changing the genetic make- up of the single-cell bacterium E.coli,and affordable growth hormone could be produced.3. Human insulin（胰岛素）一for the treatment of diabetes. People with diabetes used to rely on a beef- or-pork-based product until 1982.Now insulin can be manufactured by genetically altered bacteria.Advances in genetic engineering have continued,though they constantly must be weighed against the safety of procedures.There is clearly much more to discover.According to the passage, human interferon__________.A:is a hormone that causes diseaseB:could be used to treat cancerC:is a viral diseaseD:has been cured
