Abstract excerpt
Mitochondria are not only the major site of ATP production in cells but also an important source of reactive oxygen species (ROS) under certain pathological conditions. Because mitochondrial DNA (mtDNA) in the mitochondrial matrix is exposed to ROS that leak from the respiratory chain, this extranuclear genome is prone to mutations. Therefore, the mitochondrial genome is a rich source of single nucleotide...
