The last decade has seen a tremendous expansion of
scientific knowledge in human genetics. Our understanding of human genes and of
the genetic basis of disease has grown dramatically. Currently, more than 4, 000
diseases are known to be genetic and are passed on in families. Moreover, it is
now known that alterations in our genes play a role in such common conditions as
heart disease, diabetes, and many types of cancer. The identification of disease-related genes has led to an increase in the number of available genetic tests that detect disease or an individual’s risk of disease. New tests are being developed to detect colon cancer, breast cancer, and other conditions. Scientists are concerned not only that gene tests offered are reliable, but also that patients and health care professionals understand the limitations of such te A. it chiefly centers on predictive gene testing B. the health care for patients is not professional C. it may arouse the patients’ discomfort mentally D. it involves the DNA test and biochemistry 更多"Passage Six The last decad"的相关试题:我来回答: 提交
