The Full Story
The Human Genome Project produced a first draft sequence in 2001, followed by a more complete reference sequence in 2003. The international effort began in 1990 and involved researchers from the United States, United Kingdom, Japan, France, Germany, China, and elsewhere. It mapped roughly 3 billion DNA base pairs and identified an estimated 20,000 to 25,000 human genes. This project transformed genetics, medicine, and ancestry research.
