Chinese researchers have made a major advance in the science of gene editing by developing a new way to treat diseases that cannot be cured through existing methods.Their new gene editing tools, known as mitochondrial DNA base editors, can fix errors in the DNA inside a cell’s mitochondria.
The scientists used these editors to create rats with diseases caused by these mitochondrial DNA errors and succeeded in making the first direct corrections of these flaws in animals.These mitochondrial DNA...
