一、蓬勃发展的生物技术与新问题 70年代中期DNA重组实验所取得的进展,已在微生物或发酵工业和制药工业中生产新物质,引起了一场生物技术革命. 80年代初以来,生物技术不仅在微生物工业中,而且在医药和农业科学中,显示出了新的活力。因此,生物技术已经突破仅限于制造新物质而进入其它领域。在农业科学中,它被用来产生更具抗冻抗病能力的新品种,在医学中,它被用来创造新的诊断方法和用DNA进行治疗的新疗法.
First, the vigorous development of biotechnology and new problems The progress made in DNA recombination experiments in the mid-1970s, has been in the micro-organisms or fermentation industry and the pharmaceutical industry to produce new substances, has caused a revolution in biotechnology Since the early 1980s, biotechnology Not only in the microbiology industry, but also in medicine and agricultural science, has shown a new vitality. Therefore, breakthroughs in biotechnology have been made only in the manufacture of new substances and into other fields. In agricultural science, it is used to create new varieties that are more resistant to frost and disease, and in medicine it is used to create new diagnostic methods and new therapies that use DNA for treatment.
