Abstract

The human genome contains approximately 300 segments of mitochondrial DNA greater than 100 bp in length that were integrated during evolutionarily recent time into the nuclear chromosomes. The total number of genes encoding functional proteins in the human genome that ultimately stem from the ancestral mitochondrial genome is currently unknown, but it probably comprises a very substantial fraction of the genome.
