A number of studies have shown that ageing is associated with increased amounts of mtDNA deletions and/or point mutations in a variety of species as diverse as Caenorhabditis elegans, Drosophila melanogaster, mice, rats, dogs, primates and humans. This detected vulnerability of mtDNA has led to the suggestion that the accumulation of somatic mtDNA mutations might arise from increased oxidative damage...
Since the isolation and physical characterization of mammalian mitochondrial DNA (mtDNA) over 35years ago, numerous studies have been conducted in order to understand its structure and properties, including mode of mtDNA replication and transcription. Even today, the mode of mtDNA replication is still a matter of intense debate. We believe that Caenorhabditis elegans holds the promise of identifying...
