Coverage of human mtDNA sites on the whole human nuclear genome. Different genes are marked as follows: ATP6 and ATP8, ATPase subunits 6 and 8; COXI, COXII, COXIII, cytochrome c oxidase subunits I, II, III; CYTB, cytochrome b; ND1-6 and 4L, NADH dehydrogenase subunits; tRNA genes are indicated according to the transported amino acid. L1, Leu (UUR); L2, Leu (CUN); S1, Ser (UCN); S2, Ser (AGY). Horizontal axis = nucleotide position on mitochondrial genome; vertical axis = number of occurrences in the nuclear genome.
