Telomeres and life histories: the long and the short of it
1 Sept 2010
Abstract excerpt
Telomeres are repetitive DNA sequences at the ends of eukaryote chromosomes. Telomere loss limits the number of times cells can divide and is intimately involved in cell loss and renewal. Average telomere length in cell samples generally declines with donor age but shows substantial intraspecific variation. Telomeres are potentially of great interest to evolutionary biologists since the balance of fitness costs...
