TranslationsTelomere
telomere[′tel·ə‚mir] (cell and molecular biology) A centromere in the terminal position on a chromosome. Telomere the terminal segment of a chromosome. When chromosomes become fragmented, as through the action of ionizing radiation, some of the fragments may reunite, but they never reunite along the telomere. Consequently, telomeres prevent the joining of other segments of chromosomes. telomere
telomere [tel´o-mēr] an extremity of a chromosome, which has specific properties, one of which is a polarity that prevents reunion with any fragment after a chromosome has been broken.tel·o·mere (tel'ō-mēr), The distal end of a chromosome arm. [G. telos, end, + meros, part] telomere (tĕl′ə-mîr′, tē′lə-)n. Either of the sections of DNA occurring at the ends of a chromosome.tel·o·mere (tel'ō-mēr) The distal end of a chromosome arm; telomeres undergo dramatic changes during the progression of cancer. [G. telos, end, + meros, part]telomere region at the ends of EUKARYOTIC CHROMOSOMES, enabling the cell to distinguish between natural ends and unnatural ends, caused by chromosome breakage. The telomeric DNA comprises of hundreds of copies of a repeated sequence, to which specific proteins, called ‘telomere binding proteins’ (TBPs) bind to regulate the length of the chromosome.telomere
