On May 27, 2008, it was announced that Dr. Marjolein Kreik recently became the newest member of a very exclusive group of people. Thanks to a group of geneticists at Leiden University Medical Centre located in The Netherlands, Dr. Kreik is now the fifth person to have her DNA sequence determined. What makes this event even more notable is that she is the first woman— as well as the first European—to have had her DNA sequence confirmed. The first person to have their DNA sequence determined was James Watson, discoverer of the DNA double helix. His sequence was analyzed in 2001.
