DNA Day History

DNA Day seeks to commemorate the discovery of DNA’s double helix in 1953. DNA is a molecule that contains the genetic instructions required for development, growth, and reproduction of living beings. This day also commemorates the success of the Human Genome Project in 2003. This international research project aimed to determine the base pairs that make up human DNA. This day offers more knowledge about genetics. It also offers the opportunity to learn more about genomic research.

DNA Day was established in 2003 by the United States Senate and House of Representatives. It has been observed annually on April 25th by the National Human Genome Research Institute.
