The role of telomeres is to protect chromosome ends from damage and prevent the loss of genetic material during cell division. As cells divide, telomeres shorten slightly, but their presence ensures that the coding regions of chromosomes are not lost. They also prevent the ends of chromosomes from fusing with other chromosomes, which could lead to genomic instability. Telomeres are a key component of the cellular aging process—when telomeres become too short, cells either stop dividing or undergo apoptosis, contributing to tissue aging and the overall aging process.
