Table 1.

Number of miscoding lesions observed within chloroplast and mammoth datasets

	Miscoding lesions originally derived from A and T nucleotides				Miscoding lesions originally derived from C and G nucleotides
	A→G T→C	A→C T→G	A→T T→A	Total A+T^a	C→A G→T	C→G G→C	C→T G→A	Total C+G^b
Chloroplast	78	24	89	244 230	33	9	52	146 735
Mammoth	39	7	9	81 790	16	8	597	49 684
Corrected Mammoth^c	116	21	27		47	24	1763
Nucleotide ratio				2.99				2.95

^aTotal number of adenine and thymine nucleotides in dataset.

^bTotal number of cytosine and guanine nucleotides in dataset.

^cCorrected Mammoth: the number of observed lesions among the mammoth sequence data, scaled to match the total chloroplast nucleotides sequenced. For example, corrected mammoth count for A→G/T→C pair was calculated as (Observed Mammoth A→G/T→C)*(Total Chloroplast A+T)/(Total Mammoth A+T) = 39*244 320/81 790 = 116.
