The human genome is done. The Human Genome Project claimed victory in 2001 when it had read all of a person's genes. The remaining 8 percent of the genome was hard to decipher. The final sections were difficult to sequence due to their repetitive nature. Hundreds of new genes, including genes involved in immune responses and those responsible for humans developing larger brains, were revealed. Evan Eichler of the University of Washington is one of the co-chairs of the Telomere-to-Telomere Consortium.
