Scientists Have Completed Mapping the Last 8% Of the Human Genome
Humanity is a work in progress, and sequencing the human genome has been too. In 1990, the Human Genome Project began working to decode the fundamental building blocks of humanity: our DNA, collected into 23 chromosomes within what is called a genome. By 2003, the project had sequenced three billion chemical base pairs that make up human DNA. This phenomenally successful project eventually documented 92% of the genome.
