Recovering RNA from extinct Tasmanian tigers

The thylacine is a marsupial that is roughly the size of a dog and is covered in stripes. It is also frequently referred to as the Tasmanian tiger. In the distant past, they populated not only the mainland of Australia but also the islands that are located in the area. The fact that this animal no longer exists does not change the reality that it was an accomplished hunter. Despite this, investigators have not abandoned their efforts to learn more about them. A significant breakthrough was achieved not too long ago by a research group from the Centre for Paleontological Genetics, which was led by geneticists.

In addition, the Xylife Lab in Sweden stated that it had successfully isolated “RNA,” also known as ribonucleic acid, from the dried skin and muscles of Tasmanian tigers. RNA is another name for ribonucleic acid. Researchers have found that sequencing and analysing ancient RNA, which has been kept in storage at the Swedish Natural History Museum in Stockholm since 1891, may help in the process of recreating extinct species. These samples have been kept there since the museum opened in 1891.

There is a possibility that the genetic material that is referred to as “RNA” (RNA) is present in each and every cell of every living organism. Its structure is similar to that of “DNA,” which is also known as deoxyribonucleic acid. DNA is a molecule that is formed like a double helix and stores the genetic information for all living species. Its structure is akin to that of the structure of the molecule. Genes are the fundamental building blocks of all living things and are responsible for their growth. RNA is a single-stranded molecule, but DNA is a double-stranded molecule that carries all of the genetic information that may be read from it.

DNA is what is known as a nucleic acid. A sizeable amount of the proteins that are necessary for the survival of living things are synthesised as a result of the action of RNA, which is the catalyst for this process. and aids in the regulation of the metabolic activities occurring inside the cell Researchers think that they will be able to identify the metabolic processes that were taking place in the cells and tissues of Tasmanian tigers prior to their extinction if they sequence the RNA from the animals’ genomes. This can be done by sequencing the RNA.

The remains of a Tasmanian tiger that are now on exhibit at the museum have been preserved in a manner similar to that of a mummified animal. This reveals the amount of time that RNA may remain stable, such as when it is kept at room temperature. There is no evidence of any internal organs, yet the skin, muscles, and bones have all been preserved.

The vast majority of scholars are of the belief that the existence of RNA is just for a fleeting period of time. When stored at normal temperature, the time span is anything from one day to one week. If the body is damp or has been decomposing for some time, there is a chance that this will take place. On the other hand, it would seem that this is not the case once the leftovers have been dried out. The retrieval of RNA from ancient viruses has the potential to provide information on the variables that contributed to prior pandemics.
