Szostak, Jack William

Jack William Szostak, 1952–, American molecular biologist, b. London, England, Ph.D. Cornell, 1977. Szostak has been a professor at Harvard Medical School and a researcher at Massachusetts General Hospital since 1977. He shared the 2009 Nobel Prize in Physiology or Medicine with Carol Greider and Elizabeth Blackburn for solving the problem of how chromosomes make complete copies of themselves during cell division and how they protect themselves against degradation during this process. 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.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
