Dr. Bill Andrews, Ph.D, explains the role of Telomeres and Telomerase in Aging on Korean National Te
Inside the nucleus of a cell, our genes are arranged along twisted, double-stranded molecules of DNA called chromosomes. At the ends of the chromosomes are stretches of DNA called telomeres, which protect our genetic data, make it possible for cells to divide, and hold secrets to how we age.
Telomeres can be compared to the plastic tips of shoelaces, because they keep chromosome ends from fraying and sticking to each other, which would destroy or scramble an organism's genetic information.
Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell can no longer divide; it becomes inactive or "senescent" or it dies. Dr. Bill Andrews,Ph.D, in this recent documentary featured on National Korean Television Channel EBS1 explains how this shortening process is associated with aging, cancer and a higher risk of death.
