Mitochondrial DNA

THE ORGANIZATION AND INHERITANCE OF THE MITOCHONDRIAL GENOME is an article that is also a useful source of information about mitochondrial DNA. Not all of our DNA is located within the nucleii of our cells. Not surprisingly, mitochondrial DNA is located in mitochondria. Mitochondria are cellular energy factories and mitochondrial DNA codes for components of energy producing mechanisms.

The article discusses enzymes whose function involves the protection and organization of mtDNA. Mutations of genes, contained in mtDNA, can accelerate the ageing process and also lead to neuromuscular diseases.
