![]() ![]() Moreover, by using TRF analysis it is possible to distinguish genuine (terminal) telomeres from interstitial telomeric repeats (ITR) (Richa rds and Ausubel, 1988). Therefore, the use of frequent cutters or their mixtures is recommended to minimize this difference. As TRF include besides telomeres also a short region of telomere-associated DNA up to the first restriction site, resul ts are slightly shifted towards higher TRFs values. Fragments of telomeric DNA are then visualized by hybridization with radioactively labeled telomeric probe. Consequently, telomeres remain in relatively long fragments (TRF), whereas the genomic DNA is digested into short pieces. This technique relies on the fact that repeated minisatellite telomeric units do not contain target sites for restri ction enzymes. Term inal Restriction Fragments (TRF) analysis is the oldest approach to analyze telomere lengths and remains the “gold standard” even in current studies. Determination of te lomere lengths is an essential approach in telomere biology for research and diagnostic applications. Their shortening du e to incomplete replication functions as a molecular clock counting the number of cell divi sions, and ultimately results in cell-cycle arrest and cellular senescence. Intent(this, ExampleActivity::class.java).Chromosome ends - telomeres - are a focus of intensive research due to their importance for the maintenance of chromosome stability.
