Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

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. Cornell University ...

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells by co-opting a process used to maintain cellular identity through ...

For palaeontologists, DNA is infuriatingly fragile. Its long chains begin to break apart shortly after death, destroying valuable information about the deceased parent organism. Unlike bones, ...
