Webb17 sep. 2013 · Telomeres are protective DNA and protein complexes at the end of linear chromosomes that promote chromosomal stability. Telomere maintenance is required for the complete replication of DNA and protection of chromosomes from nuclease degradation, end-to-end fusion, and cellular senescence. Webb13 nov. 2009 · The ends of eukaryotic chromosomes have the potential to be mistaken for damaged or broken DNA and must therefore be protected from cellular DNA damage response pathways. Otherwise, cells might permanently arrest in the cell cycle, and attempts to “repair” the chromosome ends would have devastating consequences for …
Webb18 sep. 2024 · The main function of telomeres is to protect chromosome ends from being recognized as double-strand DNA damage through recruitment of shelterin, alteration of their structure and compaction of telomere chromatin. These protection mechanisms are based on the maintenance of telomere length. WebbTelomeres are the protective ends of linear chromosomes.
