"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."
