What is the News ?

Researchers have recently extracted Ribonucleic acid (RNA) from the desiccated skin and muscle of a Tasmanian tiger that had been stored at a museum in Stockholm since 1891.

Facts About:

  • The Tasmanian tiger had a wolf-like appearance, distinguished by tiger-like stripes along its back.
  • Regrettably, the last known Tasmanian tiger passed away in a Tasmanian zoo in 1936.
  • This large carnivorous marsupial is now considered extinct.
  • Among the family Thylacinidae, it stood as the sole survivor into modern times.
  • Its habitat once spanned across continental Australia, reaching as far north as New Guinea and as far south as Tasmania.
  • As an apex predator, it hunted kangaroos and various other prey.

What is RNA?

  • RNA, short for Ribonucleic acid, is a complex compound with a high molecular weight, and it plays a crucial role in cellular protein synthesis.
  • In some viruses, RNA takes on the role of carrying genetic codes, replacing DNA (deoxyribonucleic acid).
  • RNA is composed of ribose nucleotides, which are nitrogenous bases attached to a ribose sugar via phosphodiester bonds.
  • The nitrogenous bases found in RNA include adenine, guanine, cytosine, and uracil.
  • Unlike DNA, RNA is a single-stranded molecule responsible for carrying genetic information.
  • RNA's primary function is to synthesize the diverse array of proteins required by an organism for survival, while also regulating cell metabolism.
