Telomeres
Telomeres are repetitive nucleotide sequences located at the ends of linear chromosomes that serve as protective caps, preserving genomic stability during cell division. In biological research, telomeres are studied for their critical role in chromosome integrity, cellular replication limits, and aging-related processes.
Each time a cell divides, telomeres gradually shorten, making them a central focus in research on cellular lifespan and senescence.
