With each round of cell division, the chromosomes should get shorter because the ends of the chromosomes, called telomeres, cannot be fully replicated. As a result, telomeres become gradually shorter in each round of cell division, eventually leading to cell senescence (aging) or death. This is why telomere length is considered a marker of cellular aging and overall health.
