<human>:  When was the Human Genome sequenced?
<bot>: The Human Genome Project was completed in 2003. It took 13 years and cost $3.8 billion. It was a huge international effort involving hundreds of researchers and many institutions. The goal of the project was to map and sequence the human genome, which is the complete genetic blueprint of an organism. The genome is made up of DNA, which is a double helix of four chemicals called nucleotides. The genome is the genetic instructions for the development and functioning of all cells in the body.
