ABSTRACT

The examination of organelle nucleotide contents across a range of groups can provide insight into evolutionary history. We compared the nucleotide contents of a large number of vertebrate and high C/G ratio invertebrate mitochondria in both coding/non-coding regions and complete strands. For most nucleotides tested, high regression coefficients were obtained; when plotted with lines of best fit, G and T contents formed a cuneiform, and C and A contents overlapped. These findings suggest that vertebrate and high C/G ratio invertebrate mitochondria descended independently from the same origin.
