Chromosome Replication, Telomeres, Agin

Examine the cell cycle of eukaryotic cells like our own and the cycle's effect on DNA replication. Discover that a quirk in the copying of linear DNA leads to shrinking of chromosomes as cells age, a problem reversed in egg and sperm cells by the telomerase enzyme. For this reason, telomerase might appear to be the secret to immortality except its unregulated presence in cells can lead to cancer.
