Telomerase the so called 'dead sections' of DNA that cap the ends of chromosomes, are in news again.
Telomerase have been known to be involved in death of a cell. Like an eraser they keep getting shortened as the cells divide and as it reaches a critical point the cells die. Cancer cells get immortalized if the telomerase enzyme regenerates the telomerase.
Joachim Lingner of the Swiss Federal Institute of Technology in Lausanne and his colleagues have found that they the telomerase can behave like genes in that they make RNA copies of themselves (Science, DOI: 10.1126/science.1147182).
