In a groundbreaking study published in the journal Genome Research on September 20, 2023, scientists announced that they had successfully recovered RNA from an extinct species for the first time. The RNA, which was extracted from the skin and muscle of a 130-year-old Tasmanian tiger specimen, is the oldest RNA ever sequenced. RNA is a single-stranded molecule that plays a vital role in all living cells. It is responsible for carrying genetic information from DNA to proteins, and it also regulates many other cellular processes. However, RNA is much more fragile than DNA, and it breaks down quickly after death. As a result, it was previously thought that it would be impossible to recover RNA from extinct species. The researchers who conducted the study used a new technique called "RNA capture sequencing" to extract and sequence the RNA from the Tasmanian tiger specimen. RNA capture sequencing involves using short DNA probes to bind to specific RNA sequences. The probes are th...
