The Human Genome Project was discussed as early as 1985, and the initial pr
ogram began in 1990. The subsequent sequencing programmes have taken into a
ccount the rapid progress in the field, the technological advances, and the
appearance of companies from the private sector. The genetic and physical
cartography, sequencing of messengers and of the entireity of the human gen
ome were begun successively. Furthermore, a number of genomes of model spec
ies have been fully sequenced. Ninety percent of the human genome was seque
nced as of June 2000, and it is hoped that it will be finished in it's enti
rety by 2003. This should lead to the identification of all of the human ge
nes, and of genetic variations of interest.
