Mitochondrial DNA mutators

Cellular and Molecular Life Sciences, 2004
In this article we review our current knowledge of the mechanisms by which point mutations arise in the mitochondrial DNA (mtDNA) of Saccharomyces cerevisiae and discuss to what extent these mechanisms operate in human mtDNA mutagenesis. The 3'-5' exonuclease proofreading activity of Pol gamma ensures accuracy of mtDNA replication in both yeast and ...

Mitochondrial DNA Analysis

2023
Mitochondrial DNA (mtDNA) is a 16,569 base pair (bp) circular genome that is passed from generation to generation through the maternal line. mtDNA analysis in the context of the forensic science field usually involves unidentified human remains or missing persons. These cases tend to have more challenging sample types (e.g., rootless hairs, bone, blood,

Mitochondrial DNA and aging

Clinical Science, 2004
Among the numerous theories that explain the process of aging, the mitochondrial theory of aging has received the most attention. This theory states that electrons leaking from the ETC (electron transfer chain) reduce molecular oxygen to form O2•− (superoxide anion radicals).
