When the telomere is too diminished, the cell often dies or becomes pro-inflammatory. only sunscreen on face

"WebTelomeres shorten because DNA polymerase, the enzyme that replicates DNA, can only replicate DNA in one direction (directions in DNA are not thought of in terms of left/right or up/down, but instead as 5' or 3' ["5 prime" or "3 prime].) Polymerase creates DNA traveling in a 5' --> 3' direction only. " - How do telomeres shorten
