DNA Day - April 25
Thu, Apr 25, 2024


DNA Day is a worldwide holiday dedicated to DNA. It is celebrated annually on April 25. It calls to mind the history of the discovery of DNA, and unites all geneticists and doctors who are engaged in its research to study diseases and develop effective drugs for treatment.


The history of DNA Day dates back to 2003. That’s when the major research project “Human Genome” was completed, with scientists from all over the world working on it. The main goal was to study the DNA chain and determine the complete set of human genes. Its completion was celebrated by the U.S. government, which provided a great deal of funding for it. The Senate and the House of Representatives then created this celebration, in honor of historic events in the world of science!

The date of the celebration (April 25) also takes us back to 1953. At that time, the journal Nature published the results of the work of J.D. Watson, who presented the DNA molecule in the form of a double helix. It is this appearance that is generally accepted today and has remained unchanged for decades.

Interesting facts

  • In a bone marrow transplant, the patient’s blood will also contain the donor’s DNA.
  • DNA is damaged hundreds of thousands of times every day, but thanks to a sophisticated repair system, a person does not get cancer or acquire various kinds of mutations.
  • The closest representative of the animal kingdom in terms of DNA similarity to humans are chimpanzees and humanoid apes (about 95%). A funny fact is that a banana and a human share 50% of the same genes.
