Figure 1

The schematic diagram and full sequence of the Asian arowana heavy strand control region shows the presence of two repeats. Panel A: Schematic diagram of Asian arowana mitochondrial heavy strand control region. Labels: TRA – tandem repeat array; TAS – termination-associated sequence; CSB – conserved sequence block; MS – microsatellite. Panel B: The nucleotide sequence. Positions of the TACAT motif, 37-bp tandem repeat, termination associated sequences, conserved sequence blocks and the AT-microsatellite are labeled with bold.
