Figure 1. DNA primer-templates.

Figure 1

(A) Primer-templates used for photo-cross-linking studies. “B” indicates a BrdU residue and * shows the position of an α-32P-labeled dC residue in the template. Dashes indicate that the sequence is the same as the line above. Subscript “H” indicates a dideoxynucleotide residue introduced at the 3′ end of an oligodeoxynucleotide primer. (B) Primer-templates used for SA binding and SA-biotin barrier experiments. “Bio” indicates the position of the internal Biotin-ON structure (shown in panel (C)). WL50 has the same sequence as WL50-Bio39 with the Biotin-ON structure replaced by T.
