Geneticists have for the first time isolated and decoded RNA molecules from a creature that died out long ago.The genetic material — which came from a 130-year-old Tasmanian tiger, or thylacine, specimen in the collection of the Swedish Museum of Natural History in Stockholm — has allowed scientists to better understand how the animal's genes functioned. The researchers shared their findings in a study published Tuesday in the scientific journal Genome Research.
Mármol Sánchez said that while de-extinction wasn't the goal of his team's research, a better understanding of the Tasmanian tiger's genetic makeup could help recently launched efforts to bring back the animal in some form.said the paper was"groundbreaking." Ancient DNA, under the right conditions, can last for more than a million years and has revolutionized scientists' understanding of the past.
The research team was able to sequence RNA of the skin and skeletal muscle tissues from the specimen and identify thylacine-specific genes. This information forms part of what's known as the animal's transcriptome, just as the information stored in DNA is known as a genome. said. He uses an analogy of a city where every restaurant is given one huge recipe book — the DNA. However, it's RNA that allows each restaurant to produce different dishes from that reference book.
