FIG. 2.

Long and short heterologous primers are utilized by yeast telomerase at comparable efficiencies. (A) Polymerization assays were performed using 1.5 μM concentrations of either OXYT1 or OXYT2 as the DNA primer and 2.3 μg of DEAE fractions. The locations of the “+3” and “−4” products for OXYT1 and that of the “+3” product for OXYT2 are indicated by horizontal bars. (B) Polymerization assays were carried out using increasing concentrations of either OXYT1 or OXYT2, and the signals derived from direct extension of the primers were quantified and plotted.
