Mammoth Cloning - how close are we?
You may recall the Woolly Mammoth excavated by an international team of scientists. This was an intact 20,380 year old carcass that was air lifted from the permafrost on the Taimyr Peninsula of Siberia. It was brought to Khatanga (northern Siberia) where it could be kept stable for detailed research in a permafrost tunnel.
This was publicized on the Discovery Channel a few years ago (1999)

I recall watching as they took a hair dryer to it and when they reached the hairs along it back, they described it had strong animal smell. (Perhaps the same smell you would encounter, had you gotten close to one 20,000 years ago).
To be able to study an intact animal from another period, is a paleontologist's dream. There is speculation that the body is so well preserved, scientists may be able to clone him.. Granted, the chances of finding whole DNA strands are slim. However, there will be lots of fragmented DNA. With today's methods of sequencing, fragment sequences can quickly be analyzed by computer. By comparing strands with overlapping sequences, whole strands of DNA can be deduced. As I understand it, that is also how the human genome was mapped.
Once we have a complete map of all its chromosomes (and extra nuclear DNA), can we reconstruct a full set? Is the technology close at hand to make an exact copy of a species that became extinct 10,000 years ago?
Has anyone read about subsequent research completed on the Jarkov Mammoth?
