Mitochondrial DNA is the small circular chromosome found inside mitochondria. The mitochondria are organelles found in cells that are the sites of energy production. Credit: http://www.genome.gov/ (CC0)

Researchers from Caltech and UCLA have developed a new approach to removing cellular damage that accumulates with age. The technique can potentially help slow or reverse an important cause of aging. The team developed a technique to remove mutated DNA from mitochondria. There are hundreds to thousands of mitochondria per cell, each of which carries its own small circular DNA genome, mtDNA, the products of which are required for energy production...
