^*Numbers denote specific nucleotide mixtures: 5 = 70% A and 10% other nucleotides; 6 = 70% C and 10% other nucleotides; 7 = 70% G and 10% other nucleotides; 8 = 70% T and 10% other nucleotides; 9 = 90% T and 10% G. “N” denotes an equimolar mixture of all four nucleotides. “K” denotes an equimolar mixture of G and T.
