LW-USA Telomeres -
As normal cells divide, the ends of their chromosomes (telomeres) progressively shorten until eventually the cells reach senescence or undergo apoptosis. Cancers, which disproportionally kill more individuals in the 65 years or above age group, often o... -
20/20 video clip explaining how telomeres may be the key to aging. Progeria is also briefly discussed. -
Review of structure, synthesis, and function of DNA telomeres -
(Visit: http://www.uctv.tv/) Does stress speed up the aging process at a genetic level? Our cells are constantly aging. When cell divide some telomere is lost but if it becomes too short, that cell can no longer replicate and eventual dies. Elissa Epel... -

Can cells just divide and divide forever? Not if telomeres can help it! Find out more in this video. Head on over to khanacademy.org or the khanacademymedicine YouTube channel to see some really informative videos! -
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. Without the coating, shoelaces become fra...
