Telomeres arose from the need to stabilize natural chromosome ends, resulting in terminal chromatin structures with specific protective functions. Their constituent proteins also execute general functions within heterochromatin, mediating late replication and facilitating fork progression. Emerging insights into the mechanisms governing heterochromatin replication suggest telomeres and heterochromatin act in concert during development and aging. They also suggest a common evolutionary origin for these two chromosome regions that arose during eukaryogenesis.
