“2004, Peter M. Lansdorp, 11: Telomeres and Telomere Regulation, Robert Paul Lanza (editor), Handbook of Stem Cells, Volume 2: Adult and Fetal Stem Cells, page 127, Chromosome ends or telomeres are composed of guanine-rich repeat⟳ sequences and associated proteins. A minimum number⟳ of repeats is essential for proper telomere function and to avoid⟳ sustained activation of DNA damage⟳ pathways that may result⟳ in replicative senescence or cell death.”

“It has been known for some time that when cells divide⟳, causing chromosomes to duplicate, telomeres get⟳ shorter. The more a cell divides, then, the shorter the telomeres become⟳.”

“Previous studies have⟳ examined telomere lengths as an indirect measure⟳ of aging in cloned animals. Sheep were reported to have⟳ shorter telomeres suggestive of premature aging while cattle had either age-appropriate or longer telomeres.”
