Cell regulation/death

... or they receive signal to die off, they undergo the PCD. The telomeres are problem, but they measure for all the cells about the same number of divisions, so there could be no selectivity. Cancer cells are usually able to overcome that by production of telomerase, which is enzyme elongating ...
