Telomerase is a reverse transcriptase that uses an RNA template to synthesize telomeres. These repeat sequences bind special proteins that fold the ends of chromosomes back onto themselves to create a stable cap. When this cap is damaged, the cell often interprets the exposed DNA as a double strand break and attempts to ‘repair’ it. The problem with repairing chromosome […]
