<P> A telomere is a region of repetitive nucleotide sequences at each end of a chromosome , which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes . Its name is derived from the Greek nouns telos ( τέλος ) `` end '' and merοs ( μέρος , root : μερ - ) `` part '' . For vertebrates , the sequence of nucleotides in telomeres is TT A GGG , with the complementary DNA strand being AATCCC , with a single - stranded TTAGGG overhang . This sequence of TTAGGG is repeated approximately 2,500 times in humans . In humans , average telomere length declines from about 11 kilobases at birth to less than 4 kilobases in old age , with the average rate of decline being greater in men than in women . </P>
