In future will be able to more effective drugs for slowing down cellular aging.
With the greatest precision, the scientists were able to identify the device specific enzyme that recreates the protective sequences of DNA. Experts believe that in the future they will be able to more effective drugs for slowing down cellular aging and possibly cancer treatment.

At the ends of chromosomes are small areas of the genome called telomeres. They contain a more dense structure of DNA that act as “protective helmet” for chromosomes. When you factor dividing cells secrete special enzymes that copy the whole DNA sequence, but they are not able to start building a new chain from the beginning. As a result, at each cell division the length of telomerase at the end of a chromosome decreases, which leads to the process of aging in the biological sense.
Researchers from the University of California at Berkeley for the first time were able with high accuracy to determine the structure of this enzyme. Increased activity of telomerase, in fact, makes the cells immortal. A similar effect is observed, for example, in a malignant tumor: the cells in it do not age and not die, just because of the high level of telomerase.
Various groups of scientists are already actively studying the enzyme in order to determine the safest way of influencing the production and activity of the enzyme.
