Figure 2From: A fragmented metazoan organellar genome: the two mitochondrial chromosomes of Hydra magnipapillataBase composition in cnidarian mt genomes. Correlations of AT content (%) of mt rRNAs and the AT content (%) in the codon positions 1, 2 and 3 calculated from 13 protein-coding genes of 24 cnidarian mt genomes (Additional file 4). Black filled symbols = H. magnipapillata; grey filled symbols = H. oligactis.Back to article page
