Abstract:
The complete mitochondrial genome sequence of the Aetobatus flagellum is 20,201 bp long and consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 control region (CR). The base composition of the genome is 30.9% A, 28.2% T, 27.1% C and 13.8% G. Comparing mtDNA of elasmobranchs submitted in NCBI, our study not only identified the longest mitochondrial genome with 4490 bp CR in A. flagellum, but also strongly revealed that records in the northwest Pacific may belong to a separate species from those distributed in Indonesia.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
