DNA Day 2013

DNA Day is celebrated each year in April.

In April 1953, the paper by James Watson and Francis Crick describing the structure of DNA was published in the scientific journal Nature. With help from other scientists, Watson and Crick were the first to describe DNA as a double helix, or a twisted ladder shape. Notably, their model of DNA suggested how genetic information is stored and copied. DNA Day commemorates this important landmark in science.

This year, DNA Day marks the 10-year anniversary of the completion of the Human Genome Project, the 13-year international effort that identified the order, or sequence, of more than 3 billion building blocks (bases) in human DNA. The Human Genome Project was finished in 2003, 50 years after Watson and Crick described DNA as a double helix.

The National Human Genome Research Institute and other organizations will celebrate DNA day on April 25, 2013. Please use the links below to learn more about DNA Day, the discovery of DNA's structure, and the Human Genome Project.
