The term “telomere” is derived from two Greek words: “telos,” meaning “end,” and “meros,” meaning “part.” It literally refers to the “end part” of a chromosome. This reflects the telomere’s role in capping the ends of chromosomes and protecting them from damage. The telomere acts as a safeguard to prevent the loss of important genetic information during DNA replication. Without telomeres, the ends of chromosomes would be vulnerable to degradation, which could lead to genetic instability. The primary function of the telomere is to maintain the stability of chromosomes and prevent fusion with other chromosomes, which could result in chromosomal abnormalities. Over time, the telomeres shorten as a cell divides, which has been linked to aging and the eventual cessation of cellular replication.
