Extraction and sequencing of ancient DNA has revolutionized scientists’ understanding of numerous extinct species, but DNA can only tell us so much. RNA, however, can tell us which genes were actually ...

Scientists have extracted RNA from an ancient woolly mammoth that gives new insight into the extinct beasts—and might one day boost moonshot efforts to resurrect them. The animal’s body was discovered ...

To obtain high-quality, purified nucleic acids, scientists can use several different methods, including phenol-chloroform extraction, cesium chloride/ethidium bromide (CsCl/EtBr) gradient ...
