Abstract excerpt
Mitochondria have long been suspected to be among the leading determinants of aging due to their functional importance and accelerated deterioration caused by accumulation of mutations in the mitochondrial DNA. Direct repeats are known to contribute to deletion formation in mtDNA and are a powerful source of reactive oxygen species (ROS)-independent mutagenesis. To evaluate the potential importance of...
