TELOMERASES

ONCE AGAIN NATURE PLAYS IT SIMPLE FOR BIG THINGS!
ONE OF THE WAY NATURE CHECKS THE AGE OF CELLS  IS BY CHECKING THE LENGTH OF THEIR DNA SKIRT ATTACHED AT THE END OF THEIR CHROMOSOME.  ALL CELLS OF SAME TYPE START WITH A RELATIVELY SAME LENGTH OF SKIRT.  WITH ANY DIVISION, THE SKIRT IS CUT SHORTER.  IF THE SKIRT IS TOO SHORT TO EXPOSE THE END OF THE CHROMOSOME, THE CELL HAS LIVED LONG ENOUGH AND IT IS SENT FOR DESTRUCTION.  THE LENGTH OF THE SKIRT CAN BE PROLONGED BY SOME ENZYMES THOUGH TO FOOL THE CHECK SYSTEM.  THESE ENZYME ARE CALLED THE TELOMERASES.

CANCER CELLS DO NOT DIE BECAUSE THEY ACTIVATE THEIR  TEL-O-MERASE. AND EACH TIME THEY DIVIDE, THEIR TELOMERASE RESTORE THE LENGTH OR JUST GIVE THEM THE LONGEST SKIRT EVER TO BEAT THE SYSTEM!  RESEARCHERS ARE WORKING HARD TO SILENCE THE CANCER CELL TELOMERASES!  THE CRBCM IS LOOKING INTO THIS!
