Jack W. Szostak

Jack W. Szostak

Born: 9 November 1952, London, United Kingdom

Affiliation at the time of the award: Harvard Medical School, Boston, MA, USA, Massachusetts General Hospital, Boston, MA, USA, Howard Hughes Medical Institute

Prize motivation: "for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase"

Field: genetics

Prize share: 1/3

Work

An organism's genes are stored within DNA molecules, which are found in chromosomes inside its cells' nuclei. When a cell divides, it is important that its chromosomes are copied in full, and that they are not damaged. At each end of a chromosome lies a "cap" or telomere, as it is known, which protects it. After Elizabeth Blackburn discovered that telomeres have a particular DNA, through experiments conducted on ciliates and yeast, she and Jack Szostak proved in 1982 that the telomeres' DNA prevents chromosomes from being broken down.
