WebNov 13, 2015 · There’s also another key player in the game: telomerase. Telomerase is an enzyme that lengthens telomeres and keeps them from wearing out too fast or too early. But with constant cell division, telomerase levels are depleted, enabling telomeres to shorten. WebIn egg and sperm cells, an enzyme called telomerase keeps adding more of the repeating sequence onto the end of DNA strands, so that the telomeres in these cells don’t shorten.
