Figure 21-3

Maps of yeast and human mtDNAs. Each map is shown as two concentric circles corresponding to the two strands of the DNA helix. Note that the mutants used in yeast mtDNA analysis are shown opposite their corresponding structural genes. Green = exons and uninterrupted genes, red = tRNA genes, and yellow = URFs (unassigned reading frames). tRNA genes are shown by their amino acid abbreviations; ND genes encode subunits of NADH dehydrogenase. (Note that the human map is not drawn to the same scale as the yeast map.)
