Figure 6.

Effect of added DNA polymerases. (A) The effect of added Klenow fragment. The template was the 35-nt telomere DNA (TO35). The reaction conditions were identical to Figure 2B except for 4 h of reaction time and the addition of Klenow fragment (0.2 units; even-numbered lanes). The products were electrophoresed in 15% SDS-PAGE directly (upper panel) or after heat denaturation (lower panel). [α32P]-dCTP (0.165 μM) was supplemented with 10 μM non-radioactive dCTP, dATP, dGTP and dTTP as indicated. (B) The effect of added DinB1. Left panel. The polymerase activity of purified DinB1 was demonstrated by the fill in reaction on the MulI–NdeI restriction fragments (‘MN’; Figure 2B). The reaction conditions were identical to those in Figure 2B. Right panel. The extension activity on the in vitro deoxynucleotidylated product by DinB1 was tested under the same conditions as in (A). ‘Kle’, Klenow fragment; ‘Din’, DinB1; ‘–’, none added.
