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).

Computational tools unlock the secrets of the genome

In collaboration with the International Conference on Research in Computational Molecular Biology (RECOMB), Genome Research publishes a collection of 20 computational methods and their applications in genomics including spatial, single-cell, and long-read sequencing.
