mtDNA - Mitochondrial DNA - Motherline

 

Mitochondrial DNA, or mtDNA, is a very unique piece of DNA. It is a circle of DNA that is not found in the center of the cell with the 46 chromosomes. Instead the mtDNA is found inside the mitochondria or powerhouse of the cell. mtDNA is also unique because you only get one copy from your mother, who got it from her mother, who got it from her mother, who got it from her mother... you get the idea.
