Telomere
A telomere is a region of repetitive nucleotide sequences at each end of a chromatid, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes. Its name is derived from the Greek nouns telos 'end' and merοs 'part.' Telomere regions deter the degradation of genes near the ends of chromosomes by allowing chromosome ends to shorten, which necessarily occurs during chromosome replication. Without telomeres, the genomes would progressively lose information and be truncated after cell division because the synthesis of Okazaki fragments requires RNA primers attaching ahead on the lagging strand. Over time, due to each cell ...The above text is a snippet from Wikipedia: Telomere
