Function of telomeres in nucleus :Telomeres are the specialised ends of eukaryotic chromosomes, made of repeated DNA sequences (e.g. TTAGGG in humans).
They seal the ends of the chromosomes, preventing them from sticking (fusing) to other chromosomes and protecting them from degradation and loss of genes during replication.
So the function of telomeres is to seal the ends of chromosomes.
