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).

Study Shows How Transposons Exploit Telomeres in Bacteria

Transposons, or "jumping genes" – DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of antibiotic resistance.
