Mitochondrial Dna
Mitochondrial DNA (mtDNA) is the genetic material that is found in the mitochondria of cells, which are the main energy-producing organelles in the human body. It is inherited from the mother and plays an important role in the development of a person’s physical and mental health. mtDNA contains only 37 genes, which code for proteins that are used in the generation of energy (ATP) from food and to regulate the cell cycle. Mutations in mtDNA can lead to a variety of serious medical conditions, such as neurodegenerative diseases and respiratory disorders. mtDNA testing is used to diagnose such conditions and in forensics to identify individuals. mtDNA is also used in evolutionary studies to trace the human lineage and in biodiversity studies to identify species.
