Telomere in Biological Dictionary

Telomere

A telomere is a region of repetitive DNA at the ends of chromosomes, which protects the end of the chromosome from destruction. Its name is derived from the Greek nouns telos (τἐλος) "end" and merοs "part". So telomeres are not themselves genes, but neither are they ......
