Abstract
Mitochondria are cellular organelles of outstanding importance because they are responsible for energy production and the control of many processes related to cell metabolism, survival and apoptosis. They are the only cytoplasmic organelles in the animal cells to contain their own DNA, a private genetic material, the mitochondrial DNA (mtDNA), which is frequently referred as “the mitochondrial genome”. In this article, the most important features of mtDNA are reviewed, regarding its structure, functioning, transmission and relation to diseases and aging. Moreover, mtDNA has peculiar properties such as maternal transmission and elevated rates of mutation, which make it an interesting source of information about human origins, dispersion and evolution.
