Scientists have extracted RNA from a Tasmanian tiger, marking the primary time this molecule has ever been sequenced in an extinct animal.

Like DNA, RNA (ribonucleic acid) carries genetic info. However as a substitute of getting a double strand of nucleotides as DNA does, RNA is manufactured from a single strand. That makes it extra more likely to degrade over time and tougher to extract from long-dead tissue.
