telomere

Pronunciation:(TEH-loh-meer)

Definition: The ends of a chromosome. Each time a cell divides, the telomeres lose a small amount of DNA and become shorter. Over time, the chromosomes become damaged and the cells die. In cancer cells the telomeres do not get shorter, and may become longer, as the cells divide.Cancer.govPatient

Definition: The end of a chromosome. Telomeres are made of repetitive sequences of non-coding DNA that protect the chromosome from damage. Telomeres become shorter each time the cell divides.GeneticsHealth professional

telómeroExtremos de un cromosoma. Cada vez que la célula se divide, los telómeros pierden una pequeña cantidad de ADN y se acortan. Con el transcurso del tiempo, los cromosomas se dañan y las células mueren. En las células cancerosas, los telómeros no se acortan y se pueden alargar a medida que las células se dividen.Cancer.govPatient2009-10-05
