Researchers analyzed ancient RNA from the extinct creatures. Could this be a “steppingstone” in the quest to bring them back?

Scientists successfully extract RNA from a 130-year-old Tasmanian tiger, thylacine, revealing how its genes functioned before its extinction.

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