The Human Genome Project (HGP) is the most ambitious and important effort in the history of biology. It has provided a complete genetic blueprint for human life, and will provide important insights into human health and development. HGP involves a huge amount of data that is stored on computers all over the world. More than just vast amounts of DNA sequences, the project is about developing sets of integrated maps that involve genetic, physical, and sequence data. The data can be sorted, annotated and organized in many different ways using different types of database software, different analysis algorithms and different forms of interfaces. The genomic sequences of the human and the substantial portions of the mouse genome are expected to be finished by 2005. Analytical chemists took the opportunity, addressing the problem of achieving a high throughput with good sensitivity. This paper discusses how analytical chemists saved the Human Genome Project or at least gave it a helping hand.
