Answer
Telomeres are the protective caps at the ends of chromosomes, similar to the plastic tips on shoelaces. They prevent the chromosomes from fraying or sticking to each other, ensuring the stability and integrity of our genetic material. As cells divide, telomeres gradually shorten, serving as a biological clock that limits cell division and ultimately contributes to aging.
