—The mitochondrial genome maps of (A) amoeba “BB2” and (B) Pharyngomonas kirbyi. Genes encoding proteins and ribosomal RNAs are shown in boxes, transfer RNA genes are shown by lines. Boxes on the outside of the circle represent RNAs encoded on the positive strand, boxes inside are RNAs encoded on the negative strand. The duplicated “IR” regions are highlighted in grey. Single copy regions are shown in black.
