The human genome is made up of approximately 35000 genes, or three billion chemicalbase pairs. The Human Genome Project, which was an international collaborative project from 1990 to 2003, was intended to identify the genes and the sequences of chemical base pairs in human DNA. However, the project sequenced only the euchromatic regions of the genome and not the heterochromaic regions in centromeres and telomeres.
