Principle of systematic deletion transcription.

This principle is used for the construction of different deletion transformed versions of the mitogenome. To construct the delRNA3-1 transformation of the mitogenome, the 4th nucleotide following each transcribed trinucleotide is deleted. Similarly, every 4th and 5th nucleotides are deleted in delRNA3-2 transformations of the mitogenome. The nucleotide(s) highlighted are the nucleotide(s) missing in del-transcribed delRNAs. These principles work for any deletion size window of k (1 to 12) nucleotides. Where k is the number of nucleotides deleted after each transcribed nucleotide triplet.
