As you may know, National DNA Day is April 25th and commemorates the day in 1953 when a paper detailing the structure of DNA was published in Nature magazine. It also recognizes the completion of the Human Genome Project in 2003. At Family Tree DNA, we celebrate those accomplishments by having a sale on DNA tests for genealogy! Our much-anticipated DNA Day Sale is now under way and will extend through Tuesday, April 26, 2016 (11:59 PM U.S. Central).
