Balancing act at chromosome ends

...elomeres reach a "critical length" the cell can no longer multiply. This has lead many scientists to conclude that the erosion of telomeres is a key feature of the aging process, while the aberrant addition to telomere ends (and increased proliferative capacity that this endows) is an integral part of cance...
