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

/telo·mere/ (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.

telomere

(tĕl′ə-mîr′, tē′lə-)
n.
Either of the sections of DNA occurring at the ends of a chromosome.

telomere

[tel′ō·mēr]
either of the ends of a chromosome, which possess special properties, among them a polarity that prevents their reunion with any fragment after a chromosome has been broken.

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

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.
