Telomeres are an essential part of human cells that affect how our cells age. Telomeres are the caps at the end of each strand of DNA that protect our chromosomes, like the plastic tips at the end of shoelaces.
Telomeres shorten each time a cell divides and at a certain point, when they reach a critical length, the cell can no longer divide and will die. Their limited lifespan means that growing cells in laboratories can be tricky, given there can only be so many cell doublings before they give up the ghost.
