TABLE 1.

DNA oligonucleotide sequences used in this study

An example of the oligonucleotide abbreviation is as follows: T_d31(2T)/P_d18, template DNA of 31 nucleotides in length with a T in the second unpaired position after annealing to the corresponding 18-mer DNA primer. The bases that vary in similar sequences are marked in red. P_d18+5 is a primer that is annealed on a template five nucleotides further than P_d18. In each group of templates, the varying base is indicated inside parentheses: T_d31(6G). For the SPR experiments, a thiol-modified DNA primer containing a disulfide on the N² of a guanosine residue is indicated by X in the sequence. Cy3 or biotin labels are indicated next to the sequences.
