DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

UNC Catalyst aims to provide knowledge and research tools to tackle rare diseases

Freely giving researchers the tools and knowledge to tackle rare and orphaned diseases is the mission of UNC Catalyst, a new endeavor the University of North Carolina at Chapel Hill has launched with a $2 million grant from the Eshelman Institute for Innovation.
