WebbTelomere Function – Role of Telomeres. Telomeres are produced as a result of incomplete replication at the end of the chromosomes. In each replication cycle, a part of the DNA is lost. These protective end caps ensure that genetic information is preserved and not lost in the process. They play a vital role in ageing. immersive night out londonWebbChromosomes.
