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).

Researchers discover weakness in bacterial machinery that drives antibiotic resistance

Superbugs, bacteria that are immune to multiple antibiotics, pose a great challenge to modern medicine. Researchers from the B CUBE - Center for Molecular Bioengineering at TUD Dresden University of Technology and Institut Pasteur in Paris identified a weakness in the bacterial machinery that drives antibiotic resistance adaptation.
