    For all the fevered 灼手 work being done, however, science is still far away from the Brave New World vision of engineering a perfect human—or even a perfect tomato. Much more research is needed before gene therapy 治疗 becomes commonplace 司空见惯的, and many diseases will take decades 几十年 to conquer 征服, if they can be conquered at all. In the short run 在短期内, the most practical 实用 way to use the new technology will be in genetic 遗传 screening. Doctors will be able to detect 检测 all sorts of flaws 缺陷 in DNA long before they can be fixed. In some cases the knowledge may lead to treatments that delay 延迟 the attack of the disease or soften 减轻 its effects. Someone with a genetic heart disease, for example, could follow a low-fat diet 饮食. And if scientists determine that a vital 至关重要的 protein 蛋白质 is missing because the gene that was supposed to make it is defective 缺陷, they might be able to give the patient an artificial 人工的 version 版本 of the protein. But in other instances 实例, almost nothing can be done to stop the damages brought on by genetic mutations 突变. (176 words) 1.
