Woolly mammoth chromosomes reconstructed using fossilized sample:

    A team of international scientists assembled the woolly mammoths genetic code using fossilized chromosomes. The chromosomes came from a 52,000 year old carcass that was discovered in Siberian permafrost. The animal was freeze-dried on death, which essentially preserved the 3D structure of ancient chromosomes. Which are thread-like structures containing DNA. Since the scientists show the shape of the animals chromosomes, it then allows them to assemble the DNA sequence of the extinct creatures. The researches then use computer modeling to reconstruct the full 3D chromosome structure from the fossilized data. The team saw that the woolly mammoth had 28 pairs of chromosomes and saw what key genes were responsible for hair follicle development and could help explain why mammoths are woolly and elephants now a days are not. 

    In my opinion, I think all of this research these scientists have found is very fascinating and crazy to think about. As it would be cool to have a once extinct animal to be here again blows my mind. How technology has changed, and the many advancements that were made benefits all of this newly found research. I don't exactly know how I would feel if a woolly mammoth would be alive, and put on this earth again. This feels like the movie "Jurassic Park."
