The Human Genome Project was an international research effort to sequence and map all of the genes of the human genome. The project, which began in 1990 and was completed in 2003, was the first to sequence the entire human genome. The project was a collaboration between the U.S. Department
The Human Genome Project (HGP) was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying, mapping and sequencing all of the genes of the human genome from both a physical and a functional standpoint. It started in 1990 and was completed in 2003. It was the world's largest collaborative biological project. Planning for the project began in 1984 by the US government, and it officially launched in 1990. It was declared complete on 14 April 2003, and included about 92% of the genome. Level "complete genome" was achieved in May 2021, with only 0.3% of the bases covered by potential issues. The full gapless sequence containing 22 autosomes and the X chromosome was published in January 2022, making it the first fully sequenced human genome. The full sequence of the Y chromosome was only published in August 2023 due to challenges with sequencing and assembling, caused by its highly repetitive nature.
