DNA 'Telomere' Length Tied to Aging, Death Risk

telomere length

The shorter the DNA sequences found at the end of a person's chromosomes -- known as telomeres -- the higher the risk for death, a large investigation into the microscopic underpinnings of mortality contends.


The finding stems from a fresh look at the role of telomeres, and the degree to which they serve as so-called "biomarkers" of aging.

More than 100,000 participants volunteered both saliva samples and medical records for analysis and review.
