Abstract:
The complete mitochondrial (mt) genome of the saddleback clownfish Amphiprion polymnus was obtained in this study. The circular mtDNA molecule was 16,804 bp in size and the overall nucleotide composition of the H-strand was 29.59% A, 25.93% T, 15.44% G and 29.04% C, with an A + T bias. The complete mitogenome encoded 13 protein-coding genes, 2 rRNAs, 22 tRNAs and 1 control region (D-loop), with the gene arrangement and translation direction basically identical to other typical vertebrate mitogenomes. We found A. polymnus (KJ101554) and A. bicinctus (JQ030887) had the same length in the protein-coding gene ND5 with 1869 bp, while the ND5 in A. ocellaris (AP006017) was 3 bp less than that of A. polymnus and A. bicinctus. Both structures of ND5, however, could translate to amino acid successfully.

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...
