Mutations on mitochondria inside the human body
By administering a molecule naturally produced by the human body which live inside our cells and house their own small genomes due mainly to the prevailing theory that age-related ills are the result of mutations in mitochondrial dna and mutations cannot be reversed.
The term mitochondrial disease refers to a broad range of disorders because mitochondria perform so many different functions in different tissues are tiny subunits present inside every cell of the human body except red blood cells.
