Nucleotide and amino acid sequences at the junction between ND1 and tRNAIle genes in four birds a and between ATP6 and CO3 genes in four turtles b. The relevant mtDNA sequences deduced for the RNA-sequenced individual are shown together with translated amino acid sequences. An asterisk shows the position of a stop codon. In a, the ND1 and tRNAIle genes of U. epops and A. monachus are overlapped without a polyadenylation site at the 5′ end of the tRNAIle gene. In the other two birds, there is no gene overlap and the polyadenylation occurs at the 5′ end of the tRNAIle gene. In b, ATP6 and CO3 genes of P. castaneus are overlapped without a polyadenylation site at this junction. In the other turtles, there is no gene overlap and the processing and subsequent polyadenylation at the junction can create stop codons for the ATP8/ATP6 mRNAs
