端粒（英語：Telomere）是真核生物染色體末端的DNA重複序列，作用是保持染色體的完整性和控制細胞分裂週期。
In 1975–1977, Elizabeth Blackburn (b 1948), working as a postdoctoral fellow at Yale University with Joseph G. Gall, discovered the unusual nature of telomeres, with their simple repeated DNA sequences composing chromosome ends.[6] Blackburn, Carol Greider, and Jack Szostak were awarded the 2009 Nobel Prize in Physiology or Medicine for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.[7]
Blackburn was appointed a member of the President's Council on Bioethics in 2002.[21] She supported human embryonic cell research, in opposition to the Bush administration. Her Council terms were terminated by White House directive on 27 February 2004.[22] Dr. Blackburn believes that she was dismissed from the Council due to her disapproval of the Bush administration's position against stem cell research.[23
