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).

New Insights into the Mechanisms of Gene Misbehavior

Researchers have discovered that a startlingly widespread occurrence in the healthy human population is "gene misbehavior," or the state in which genes are active when they should be inactive.
