| Found in | Work cat.: 94-33104: Kipling, D. The telomere, 1995. MeSH browser, Mar. 31, 2020 (Telomere. SN A terminal section of a chromosome which has a specialized structure and which is involved in chromosomal replication and stability. Its length is believed to be a few hundred base pairs. UF Telomeres. BT Chromosome Structures) Cerchiara, J.A. Telomere dynamics in Magellanic penguins (Spheniscus magellanicus), 2015: p. 3 (Telomeres, tandem repeating, non-coding sequences that protect the coding regions of DNA during cell replication, are linked to survival. Telomeres shorten with age in most species) A dictionary of biology, 2019 (telomere: The end of a chromosome, which consists of tandemly repeated short sequences of DNA that perform the function of ensuring that each cycle of DNA replication has been completed. Each time a cell divides some sequences of the telomere are lost; eventually (after 60-100 divisions in an average cell) the cell dies (the telomere theory of ageing (see senescence) is based on this phenomenon). Thus for a limited period telomeres provide protection for the genes located at the ends of the chromosome.) Oxford dictionary of biochemistry and molecular biology, 2008 (telomere: the DNA-protein structure that seals either end of a chromosome. Telomeric DNA consists of simple tandemly repeated sequences specific for each species) Merriam-Webster dictionary online, Mar. 31, 2020 (telomere: the natural end of a eukaryotic chromosome composed of a usually repetitive DNA sequence and serving to stabilize the chromosome) |
