Location: mitochondrial (mt) DNA
Every human cell has a "second" genome, found in the cell's energy-generating organelle, the mitochondrion. Comparison of control region sequences of mt DNA reveals that most people have a unique pattern of single nucleotide polymorphisms (SNPs). These sequence differences, in turn, are the basis for far-ranging investigations on human DNA diversity and the evolution of hominids.
