We'll crack the genetic code and conquer cancer. In l9th-century operas, when the heroine coughs in the first act, the audience knows she will die of tuberculosis in Act 3. But thanks to 20th-century antibiotics, the once-dreaded, once-incurable disease now can mean nothing more serious than taking some pills. As scientists learn more about the genetic code and the way cells work at the molecular level, many serious diseases -- cancer, for one--will become less threatening. Using manufactured "therapeutic" viruses, doctors will be able to replace cancer-causing damaged DNA with healthy genes, probably administered by a pill or injection.

我们将破译遗传密码并征服癌症。19世纪的歌剧中，如果女主角在第一幕中咳嗽的话，观众便会知道她将在第三幕中因肺结核而死。但是由于20世纪抗生素的出现，曾经是那样可怕的不治之症现在成了服点儿药片就万事大吉的事情。由于科学家对基因密码更加了解，而且已将研究深入到了分子水平，许多严重的疾病（比如癌症）对人类的威胁将会变得越来越小。通过使用生产出的“治疗性”病毒，科学家们得以用健康的基因取代受癌症破坏的脱氧核糖核酸。或许这一过程只是通过一粒药片或是一剂注射便可完成。
