BACK FROM THE DEAD?

SCIENTISTS CLOSER TO CLONING TASMANIAN TIGER

 

Around the world, hundreds if not thousands of species of animals (threaten) with extinction... but the latest scientific developments could mean that one day even extinct animals may back(bring back) to life using DNA technology. The last-known Tasmanian tiger died in a zoo in Hobart, Australia, in 1936. Fifty years later, the species (declare) extinct. But in 1999, a research project into DNA cloning up (set up) at the Australian Museum in Sydney, and now, after three years work, high quality DNA (extract) from a baby tiger which (preserve) in a jar of alcohol since 1866. According to scientists, there is now a chance of the Tasmanian tiger (resurrect) using techniques similar to those which (use) to create cloned sheep in the 1990s.

          If undamaged DNA (recover), it could (insert) into the empty egg of a related living species, such as a Tasmanian Devil.

However, the technology for the final stage of cloning - where the Tasmanian Tiger's DNA could (place) into a Tasmanian Devil host which (strip) of its own genetic material - is still to (develop).

"It's a very significant breakthrough," said Professor Michael Archer, Professor of Zoology at the University of New South Wales. "Although there's still a lot of work (do), there's now a real possibility of Tasmanian tigers (release) into the wild within the next decade."
