NATIONAL DNA DAYOn April 25th, people across the nation recognize National DNA Day. On this day in 1953, James Watson and Francis Crick formally announced their discovery of deoxyribonucleic acid (DNA) in a short letter published in the science journal, Nature. Fast forward to 1990, when scientists from around the world came together to begin mapping the human genome. Known as The Human Genome Project, approximately 2000 scientists in six countries set to work mapping the nucleotides in human DNA. In the process, the project learned that humans share genes with other species. Some of the species the project mapped included yeast, mice, and the fruit fly – all species commonly studied in science already.So on this celebration day let's learn about genetics and genomics .
