Telomeres

Lots of interest currently into relationship of telomere length on aging - or vice versa.

Telomeres are a  region of repetitive nucleotide sequences at the end of chromosone which reduce in length over time - therefore hinting they may be involved in the aging prcess, i.e. length reduces to zero and cell blows up (I'm simplifying slightly!)
