**4. General conclusion**

We find high reproducibility in swinger RNA coverage for the human mitogenome when comparing two independent transcriptomic datasets produced by Illumina sequencing. Positive correlations occur at each gene and transformation levels, reaffirming the reproducibility of the results, but are stronger at the transformation than gene level. The reproducibility of the swinger transcriptome in the giant virus *Mimivirus* and the ability to predict swinger RNA abundances from mathematical symmetry and error correcting principles [31, 50] together with present results from mitochondrial transcriptomes hint that swinger polymerizations are a universal phenomenon.
