DNA Day was instituted as a one-time celebration in the United States by a proclamation of the US Congress in 2002.

Double Helix

April 25 was chosen as the day to acknowledge the contribution of genetics because on this day in 1953, scientists James Watson, Francis Crick, and their colleagues published the double helix structure of DNA in the journal, Nature.

Worldwide Celebration

While DNA Day was first commemorated in the United States in 2003, it is now celebrated around the world. In the US, the National Human Genome Research Institute (NHGRI) is at the helm of organizing celebrations for the day. Universities and scientific organizations around the world also celebrate DNA day by organizing scientific conferences, educational outreach, online discussions and essay competitions.

The holiday is also called International DNA Day and World DNA Day.

How to Celebrate?

  • Attend scientific lectures to learn about the advances made in genetics.
  • Learn more about DNA, its structure, and its components. Read up about how it affects our daily lives.
  • If you have kids in your life, make a 3-D model of DNA with them. Get creative – use materials you can find at home or in your kitchen.
