Human chromosomes (grey) capped bi telomeres (white)

A telomere is a region o repetitive nucleotide sequences at each end o a chromosome, which pertects the end o the chromosome frae deterioration or frae fusion wi neeghbourin chromosomes. Its name is derived frae the Greek nouns telos (τέλος) "end" an merοs (μέρος, root: μερ-) "pairt". For vertebrates, the sequence o nucleotides in telomeres is TTAGGG, wi the complementary DNA strand bein AATCCC, wi a single-strandit TTAGGG owerhang.[1]
