Human Genome Project
Begun formally in
1990, the US Human Genome Project was an inter-
national effort coordinated by the US. Its goals
included the identification and sequencing (order-
ing) of all the bases in the human genome. US par-
ticipation in this monumental undertaking was sup-
ported by funds from the National Institutes of
Health (NIH) and the Department of Energy (DOE).
The project was successful.
