Figure 2. Schematic illustration of the non-coding regions of the mitochondrial minichromosomes of the elephant louse, Haematomyzus elephantis.

USFB1567 and ELR are the primers used to amplify the coding regions of all mitochondrial minichromosomes. A 346-bp unit (in green) repeated twice and a 225-bp unit (in yellow) repeated 4 times; the sequence similarity between/among the repeat copies of each unit is ~85%. A 99-bp sequence (in red) is present only in T-nad1-Q minichromosome.
