The Human Genome Project (HGP) was an immense international enterprise: probably the biggest biological experiment yet attempted. Researchers worked together to read the entire sequence of the DNA letters (bases) in the human genome - more than 3,000,000,000 of them. The 'gold standard' sequence was announced in 2003 and published in 2004. Yourgenome.org presents an animation of how the human genome was sequenced during the publicly-funded Human Genome Project.
