德国柏林NOXXON制药公司和丹麦奥尔胡斯大学的研究人员合作,发现了一种镜像对称的DNA分子,它不会被免疫系统识别,也不会被酶分解,可以在体内长期存活。这项成果可为利用基因技术治疗癌症等疑难疾病开辟新的途径。自然界里对称现象起着重要的作用,在人类和动物世界里到处可以看到对称现象,两条胳膊、两条腿、两个鼻孔、两个肺叶、一张漂亮对称的脸。然而抛开人体的外观,在构成人类基因的微观物质世界里,对称现象似乎并不那么明显,核苷酸和氨基酸是构成DNA、RNA和蛋白质的 In collaboration with researchers at NOXXON Pharmaceuticals in Berlin, Germany, and the University of Aarhus in Denmark, the researchers found a mirror image of a DNA molecule that is not recognized by the immune system, is not enzymatically disrupted, and can survive long in the body. This result opens up new avenues for using genetic technologies to treat difficult diseases such as cancer. Symmetry in nature plays an important role. Symmetry can be seen everywhere in the human and animal world, with two arms, two legs, two nostrils, two lobes and a beautiful, symmetrical face. However, aside from the appearance of the human body, the phenomenon of symmetry does not seem obvious in the micro-physical world that makes up the human genome. Nucleotides and amino acids constitute the DNA, RNA, and protein
