RNA extracted from an extinct species for the 1st time

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

Like DNA, RNA (ribonucleic acid) carries genetic information. But instead of having a double strand of nucleotides as DNA does, RNA is made of a single strand. That makes it more likely to degrade over time and harder to extract from long-dead tissue.
