  2. Relationship between telomeres and longevity - Wikipedia

    en.wikipedia.org/wiki/Relationship_between...

    Extending telomeres can allow cells to divide more and increase the risk of uncontrolled cell growth and cancer development. [24] A study conducted by Johns Hopkins University challenged the idea that long telomeres prevent aging. Rather than protecting cells from aging, long telomeres help cells with age-related mutations last longer. [13]

  3. Telomere - Wikipedia

    en.wikipedia.org/wiki/Telomere

    Telomere length varies greatly between species, from approximately 300 base pairs in yeast [24] to many kilobases in humans, and usually is composed of arrays of guanine-rich, six- to eight-base-pair-long repeats. Eukaryotic telomeres normally terminate with 3′ single-stranded-DNA overhang ranging from 75 to 300 bases, which is essential for ...

  4. Telomeres in the cell cycle - Wikipedia

    en.wikipedia.org/wiki/Telomeres_in_the_cell_cycle

    This problem makes eukaryotic cells unable to copy the last few bases on the 3' end of the template DNA strand, leading to chromosome—and, therefore, telomere—shortening every S phase. [2] Measurements of telomere lengths across cell types at various ages suggest that this gradual chromosome shortening results in a gradual reduction in ...

    Telomeres are like protective caps of DNA at the end of our chromosomes. Longer telomeres are associated with longer lifespans, while shorter telomeres may potentially contribute to higher rates ...

  6. Cellular senescence - Wikipedia

    en.wikipedia.org/wiki/Cellular_senescence

    As the cell divides, the telomeres on the end of a linear chromosome get shorter. The telomeres will eventually no longer be present on the chromosome. This end stage is the concept that links the deterioration of telomeres to aging. Top: Primary mouse embryonic fibroblast cells (MEFs) before senescence. Spindle-shaped.

  7. Biological immortality - Wikipedia

    en.wikipedia.org/wiki/Biological_immortality

    This does not however make them immortal in the traditional sense, as they are significantly more likely to die at a shell moult the older they get [citation needed]. Their longevity may be due to telomerase, an enzyme that repairs long repetitive sections of DNA sequences at the ends of chromosomes, referred to as telomeres.
