DNA of Woolly Mammoth Fully Sequenced

jd writes "Scientists have decoded the mitochondrial DNA of the Woolly Mammoth. According to the article: 'the Mammoth was most closely related to the Asian elephant rather than the African Elephant. The three groups split from a common ancestor about six million years ago, with Asian elephants and mammoths diverging about half a million years later.' This work is tied into efforts by researchers to use DNA to analyze other extinct species, such as the cave bear, the Haast eagle and the American lion. The novel aspect of this latest work is that it involved stitching together almost 50 fragments of mtDNA in order to obtain the sequence as a whole."

Mitochondrial DNA!

[BWJones]

The title is somewhat misleading as it should be noted that mitochondrial DNA is not genomic DNA from a cells nucleus. It is a much smaller genome from the mitochondrion that evolutionarily is thought to be descended from bacteria and is much easier to sequence from a total work perspective. Although the information that can be extracted from the analysis of mitochondrial DNA can be more informative as to lineage and evolutionary cladistics.

Come on folks, this is junior high biology.....

Incorrect title (again)

[FalconZero]

Contrary to the title, the Wooly Mammoth DNA has not been fully sequenced. The Mitochondrial DNA has, but that's nowhere near the amount of DNA in the neucleus. So don't worry, we won't be seeing Jurasic park any time soon.
