Telomeres are regions of repetitive DNA sequences at the ends of a chromosome (shown red-tinted),which protect the ends of the chromosome from deterioration or from fusing with neighbouring chromosomes. Telomeres allow for the complete replication of DNA although they,themselves,may be lost in the process. They are replaced by an enzyme called telomerase | |
