For biologists everywhere, April 25 is auspicious. It is DNA Day and commemorates the date in 1953 when scientists Francis Crick, Rosalind Franklin, James Watson and Maurice Wilkins published seminal scientific papers describing the helical structure of the DNA molecule. In 2003, April 25 was used to announce the completion of the Human Genome Project. Now annual festivities on this day celebrate the molecule of life with new discoveries. What better time to provide a new picture of DNA.
