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).

Experts introduce new gene therapy approach for muscle weakness

Experts at Children’s National Hospital have created a new pre-clinical gene therapy for the rare condition limb-girdle muscular dystrophy (LGMD) 2B.

Scientists discover how sponginess of stem cell nuclei controls cell differentiation

Researchers from Tokyo Metropolitan University have discovered how the sponginess and stickiness of stem cell nuclei controls how they "differentiate" into specialized cells. They found that the nucleus starts solid-like but becomes more fluid-like over time.
