联合王国的科学家利用三个人的DNA创造了健康的婴儿,以预防米托氏体疾病。 Scientists in the UK have created healthy babies using DNA from three people to prevent mitochondrial diseases. 这种创新的IVF技术使用捐赠者健康的线粒体DNA替代母亲的有缺陷的DNA,这可能造成严重的遗传疾病。 This innovative IVF technique uses a donor's healthy mitochondrial DNA to replace faulty DNA from the mother, which can cause severe genetic diseases. 8个婴儿出生时没有这些疾病,这种方法在英国和澳大利亚是合法的,但在美国则不是。 Eight babies have been born without these diseases, and the method is legal in the UK and Australia but not in the US. 捐赠者的基因贡献微乎其微,不到儿童DNA总量的1%。 The donor's genetic contribution is minimal, less than 1% of the child's total DNA.
