    The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [ 1 ] [ 2 ] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of cells . [ 3 ]

  4. 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 ...

  6. Biological immortality - Wikipedia

    en.wikipedia.org/wiki/Biological_immortality

    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. Telomerase is expressed by most vertebrates during embryonic stages but is generally absent from adult stages of life. [ 23 ]

  7. 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.
