Figure 4.
Mitochondrial DNA. D-loop is shown in red. The genes that encode the subunits of complex I (ND1–ND6 and ND4L) are shown in green; cytochrome c oxidase (COI–COIII) is shown in purple; cytochrome b of complex III is shown in blue; and the subunits of the ATP synthase (ATPase 6 and 8) are shown in orange. The genes for the two rRNAs (12S and 16S) are shown in pink and 22 tRNAs (F, V, L1, I, M, W, D, K, G, R, H, S1, L2, T, P, E, S2, Y, C, N, A) are indicated by boxes in yellow. The Origins of Heavy-strand replication (OH) and Light-strand replication (OL) are shown.
