WebOct 1, 2014 · Telomeres are a protective casing at the end of a strand of DNA. Each time a cell divides, it loses a bit of its telomeres. An enzyme called telomerase can replenish it, but chronic stress and cortisol exposure decrease your supply. When the telomere is too diminished, the cell often dies or becomes pro-inflammatory. WebNormal Function. The TERT gene provides instructions for making one component of an enzyme called telomerase. Telomerase maintains structures called telomeres, which are composed of repeated segments of DNA found at the ends of chromosomes.
