DNA News and Research

RSS

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).

Scientists solve structure of gene regulator that plays key role in cancer

Scientists at The Wistar Institute have collaborated on a major advance in understanding a gene regulator that contributes to some of the deadliest cancers in humans.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).
