Logo. The Human Genome Project (HGP) was an international scientific research project with the goal of determining the sequence of chemical base pairs which make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and functional standpoint.he project did not aim to sequence all the DNA found in human cells. It sequenced only euchromatic regions of the genome, which make up about 90% of the genome. The other regions, called heterochromatic are found in centromeres and telomeres, and were not sequenced under the project.
