WebTelomerase is the essential reverse transcriptase required for linear chromosome maintenance in most eukaryotes. Telomerase supplements the tandem array of simple-sequence repeats at chromosome ends to compensate for the DNA erosion inherent in genome replication. The template for telomerase reverse transcriptase is within the RNA … WebTelomerase, seen here in PDB entry 6d6v, is a molecular machine that includes a template for the telomere repeat, and an enzyme that builds the repeat onto the end of chromosomes. The template is encoded in a short RNA strand (TER), which also includes non-coding regions that interact with the rest of the telomerase complex.
