The Tasmanian tiger, or Tasmanian tiger, is a striped marsupial about the size of a dog. In the past, they lived on the Australian continent and neighboring islands. It is an excellent hunter, despite its extinction. But researchers did not stop studying it. Recently, a research team led by geneticists from the Center for Fossil Genetics. The Xylife laboratory in Sweden said it had recovered “RNA” (RNA, or ribonucleic acid) from the dried skin and muscles of Tasmanian tigers. Stored since 1891 in the Swedish Natural History Museum. In Stockholm, researchers reveal sequencing and analysis of ancient RNA that may help reconstruct extinct species.
“RNA” (RNA) is the genetic material found in all living cells. Its structure is similar to “DNA” (DNA or deoxyribonucleic acid), the double-helical molecule that contains the genetic code of living organisms. There are genes that give rise to all living things. While RNA is a single molecule that carries genetic information from DNA. Putting this information into practice, RNA makes many proteins that organisms need to survive. It works to control cell metabolism. Researchers say that RNA sequencing will reveal the metabolic controls that occurred in the cells and tissues of Tasmanian tigers before their extinction.
As for how long RNA can remain, as it does at room temperature, the remains of a Tasmanian tiger are in the museum in a semi-mummified state. Still maintains skin, muscles and bones but no internal organs Most researchers believe RNA only lasts a short period of time. Just a day or a week at room temperature. This may be the case when the carcass is dead or wet. But this does not appear to be the case when the remains are dry, as recovering RNA from ancient viruses could help decipher the causes of past epidemics.
