LONDON, Apr. 15, 2010 (Reuters) — British scientists have mastered a controversial technique using cloning technology to prevent some incurable inherited diseases by swapping DNA between two fertilized human eggs.
The resulting embryo inherits nuclear DNA, or genes, from both its parents but mitochondrial DNA from a second "mother" who donated the healthy egg. In humans, about 37 genes are found in the mitochondria -- the rest of the more than 20,000 known genes are in the DNA found in the nucleus.
