Telomere |
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 neighbouring chromosomes. |
|
|
Telomerase |
the enzyme in a eukaryote that repairs the telomeres of the chromosomes so that they do not become progressively shorter during successive rounds of chromosome replication. Telomerase, active in normal stem cells and most cancer cells, is normally absent from, or at very low levels in, most somatic cells. |
