Oldest RNA Ever Found in an Ancient Woolly Mammoth Leg

Oldest RNA ever found in an ancient woolly mammoth leg

Scientists have sequenced RNA from a nearly 40,000-year-old woolly mammoth leg, the oldest ancient RNA ever recovered. These fragile molecules could reveal which genes were active in the animal’s final hours and what was happening inside the animal’s muscles when it died.Continue ReadingCategory: Biology, ScienceTags: DNA, RNA, Wooly mammoth, Fossils

RNA Molecules Discovered in 39,000-Year-Old Woolly Mammoth Tissue

Researchers have successfully extracted and sequenced ancient RNA from the tissues of 10 woolly mammoths preserved in permafrost. One of these specimens is estimated to be 39,000 years old, making it the oldest ancient RNA sequence recorded to date. Marmol Sanchez et al.
