Szostak and Blackburn discovered that a unique DNA sequence in telomeres (the region of DNA at the ends of the chromosomes) protects the chromosomes from degradation. In addition to increasing understanding of the cell, the three researchers's work shed light on disease mechanisms and stimulated the development of potential new disease therapies.
