美国科学家最近确定一种使人容易得哮喘病的基因 ,据信这是科学家首次明确一种哮喘病基因的化学组成和在染色体上的位置。美国南加州圣冠纳公司的研究人员在距离南非大约 2 40 0公里的大西洋中一个孤岛上发现 ,岛上 30 %的居民都患有遗传性哮喘。研究人员对其中 30 0人的 DNA组 Recently, scientists in the United States have identified a gene that makes asthma easy to get, which is believed to be the first time that scientists have identified the chemical composition and chromosomal location of a gene for asthma. Researchers at San Gabriel’s company in Southern California found on an island in the Atlantic Ocean about 2 40 kilometers south of South Africa that 30% of the population on the island have inherited asthma. Researchers to 30 of them DNA group
