1 Telomerase is an enzyme that adds the TTAGGG telomere sequence to the ends of chromosomes. 2  Telomerase is only found in very low concentrations in our somatic cells. 3  Because these cells do not regularly use telomerase they age leading to a reduction in normal function.4  The result of ageing cells, is an ageing body.
