Question: Which of the following is NOT a step in the mechanism of action of telomerase? Question options: After a round of DNA extension, telomerase can reposition itself to processively synthesize subsequent telomere repeats. Each time telomerase extends the 3' end of single-stranded DNA, it does so by a length of three telomere repeats. Telomerase initially associates with the ends of linear DNA through annealing using its noncoding telomerase RNA. Extension of single-stranded DNA in the 3' direction involves a form of reverse transcription that is guided by the noncoding telomerase RNA template in telomerase.
