Here are the essential concepts you must grasp in order to answer the question correctly.
Telomeres
Telomeres are repetitive nucleotide sequences located at the ends of eukaryotic chromosomes. They protect the chromosome ends from deterioration and prevent them from fusing with neighboring chromosomes. Each time a cell divides, telomeres shorten, which is associated with aging and cellular senescence.

Chromosome Stability
The stability of chromosomes is crucial for maintaining genetic integrity during cell division. Telomeres play a vital role in chromosome stability by preventing the loss of essential DNA sequences during replication. This stability is essential for proper cell function and the prevention of genetic disorders.

Cellular Aging
Cellular aging, or senescence, is the process by which cells lose the ability to divide and function effectively over time. Telomere shortening is a key factor in this process, as critically short telomeres trigger cellular stress responses that lead to growth arrest. Understanding this relationship helps explain the biological mechanisms of aging and age-related diseases.
