美国加利福尼亚理工学院的科学家发现,百岁以上的老人有一种共同的基因突变,科学家表示这一发现有助于找到避免老化的方法。加利福尼亚理工学院进行的一项研究中发现,百岁老人在线粒体 DNA 上出现相同突变的几率比其他人高5倍。分子生物系教授阿塔尔迪博士说:“突变改变了 Scientists at the California Institute of Technology found that a common mutation in a person over the age of 100 has scientists say the discovery could help find ways to avoid aging. A study by the California Institute of Technology found that centenarians had a five-fold higher chance of developing the same mutations in mitochondrial DNA than others. Dr. Ataldi, a professor of molecular biology, said: "The mutation has changed
