Telomeres


Telomeres are caps at each end of a chromosome consisting of tandemly repeated nucleotide sequences, and have been proposed as markers of biological aging because they shorten with each cell division.  Telomere length varies considerably between individuals of the same age, and the rate of telomere shortening has been linked to oxidative stress and inflammation, both of which are implicated in biological aging.
