Answer :
The current research on telomerases is particularly useful in the fight against cancer because it shows, if telomerase activity was ceased in cancer cells, their telomeres would reduce until they had gain a 'critical length'. This would stop the cancer cells from splitting uncontrollably to form tumors.
Telomerase has been identified as a important factor differentiating cancer cells from normal cells , since it is either untraceable or has low level of activity in normal cells. Thus, it has become a very hopeful target for an anticancer therapy. The researches shows that a normal human cell can replicate and divide forty to sixty times before it cannot divide any further, and will collapse by programmed cell death or apoptosis.
