Telomere

Repetitive nucleotide sequences (TTAGGG in humans) that cap the ends of chromosomes, protecting them from degradation and fusion. Telomeres shorten with each cell division, and their length is considered a biomarker of cellular aging. Research has explored the relationship between certain peptides (particularly Epitalon/Epithalon) and telomerase activity, the enzyme responsible for telomere maintenance. This area of peptide research intersects with longevity and anti-aging science.
