Since 2003, scientists, biologists, and genetics enthusiasts have gathered on April 25 to celebrate National DNA Day, honouring the discovery and research of DNA as well as the scientific advancements that made progress possible. National DNA Day is an annual event sponsored by the Human Genome Research Institute that encourages people to learn more about the science that makes them genetically distinct.

The background of National DNA Day

The academic paper describing DNA’s double-helix structure, co-authored by American molecular biologist James Dewey Watson with British molecular biologists Francis Crick and Maurice Wilkins, was published in the scientific journal Nature on April 25, 1953. The three scientists were granted the Nobel Prize in Physiology or Medicine nine years later for their discovery of the molecular structure of nucleic acids and its significance in the transfer of genetic information in living organisms.

On April 14, 2003, the Human Genome Project, an international scientific research endeavour with the objective of determining the base pairs that comprise human DNA and identifying all genes of the human genome, was deemed complete. The endeavour lasted 13 years, was completed two years early, and was publicly funded by the United States government. It was initially intended to map the nucleotides within a human haploid genome, but scientists quickly realised that each individual’s genome is completely unique. Therefore, mapping the human genome required mapping the DNA of a small number of individuals and piecing them together to create a complete sequence for each chromosome. In other words, the complete human genome is more of a mosaic than a representation of any particular individual.

After the conclusion of the Human Genome Project, both the Senate and the House proclaimed April 25, 2003 as DNA Day and April as Human Genome Month. The day marked 50 years since the publication of Watson, Crick, and Wilkins’ academic paper, and the month was deemed significant in genome discovery. However, they only designated it as a one-time event, not an annual holiday. Since then, the National Human Genome Research Institute has hosted National DNA Day events and celebrations to encourage further research as well as commemorate and acknowledge all of the hard work that has been devoted to the study of DNA.

HOW TO PARTICIPATE IN NATIONAL DNA DAY

Take a DNA test

As a result of the scientific advances made by the HGP and Watson, Crick, and Wilkins, we now have programmes such as 23&Me and Ancestry that allow us to trace our family history using our DNA. Invest in a DNA test to satisfy your curiosity and learn more about yourself and your family.

Participate in a local event

National Human Genome Research Institute annually hosts National DNA Day events. Check out their events page if you’d like to attend a local event or host one for your city.

Have an honest discussion with your family.

The quickest method to discover your genetic history, with added allegorical context, is through your family’s stories. Even though family stories are often like a decades-long game of telephone, where some information may not be entirely accurate, there is a sense of pride in hearing the tales that led to your ability to exist today.
