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).

Rutgers scientists create CRISPR-edited mice to study the neurobiology of Tourette disorder

In research that may be a step forward toward finding personalized treatments for Tourette disorder, scientists at Rutgers University–New Brunswick have bred mice that exhibit some of the same behaviors and brain abnormalities seen in humans with the disorder.
