Mitochondrial DNA
Mitochondrial DNA (mtDNA) is a type of genetic material found in mitochondria, the energy-producing structures within our cells. Unlike the DNA in the nucleus, which we inherit from both parents, mtDNA is passed down only from mother to child. It is circular in shape and contains genes important for energy production. Scientists study mtDNA to understand evolution, track ancestry, and investigate certain diseases linked to mitochondrial dysfunction. Because of its maternal inheritance, mtDNA can provide insights into maternal lineages in genealogy and human evolution.

Mitochondrial DNA (mtDNA) is a type of genetic material found in mitochondria, the energy-producing structures within our cells. Unlike the majority of our DNA, which is inherited from both parents, mtDNA is passed down exclusively from mothers to their children. This unique inheritance pattern makes mtDNA useful for studying maternal lineage and evolutionary history. It contains genes essential for producing the proteins needed for mitochondrial function, playing a crucial role in energy production. Research on mtDNA has also contributed to understanding diseases, aging, and population migrations.
