Telomere Length

Meaning

Telomere length is a specific biomarker that measures the span of the repetitive DNA sequences and associated proteins that cap the ends of eukaryotic chromosomes, functioning to protect the genetic material during cell division. As cells divide, telomeres naturally shorten, and their length is considered a primary indicator of cellular age and replicative senescence. Clinically, telomere length is correlated with biological aging and the risk of age-related diseases.
