The human telomerase RNP can catalyze multiple rounds of repeat addition on the same telomeric substrate in vitro. Before initiating synthesis of another repeat, telomerase undergoes a translocation step to reposition itself on the telomere. Base pairs in the DNA/RNA hybrid are unannealed, the RNA template is repositioned relative to the active site, and the template base-pairs at the 3' end of the newly synthesized DNA. The anchor site interaction with DNA 5' of the RNA-DNA duplex is thought to maintain the interaction of telomerase with DNA during the translocation step.
