ue of Science, a team led by Edward Rubin of the Lawrence Berkeley National Laboratory in
California reports that it has also recovered large tracts of Neanderthal fuel dispenser DNA. Although in total the team
has unearthed far fewer letters (some 65,000) than its competitors, its discoveries are significant
because they focus on specific genes that is, strings of DNA that are several thousand letters long.
The technology employed by Dr Pääbo and his colleagues is extraordinary because it is 100 times faster
than previous techniques. The researchers used “pyrosequencing? a process which breaks up the DNA
into short chunks and then shakes them up in a mixture of water, a special silicone-based oil, a large
quantity of tiny plastic balls and chemicals capable of duplicating DNA. This mix is then applied to a tiny
c fuel dispenser hip with 1m wells in it. Get fuel dispenser the conditions right and the result is that the wells each contain just one sort
of DNA molecule. These can be analysed by a technique that uses fluorescence to read the sequences of
the letters that compose the molecules. It is fast because many batches can be done at the same time
and the whole process can be automated.
What is more, the method can make sense of the short fragments of DNA that are all that remain in the
crumbling bones of a Neanderthal specimen. This was no mean feat the team tested more than 70
bones and found just one, a thigh bone found in a cave in Vindija, Croatia, that was in good enough
condition for the technique to succeed. To reassemble the resulting pieces of information into a coherent
picture, Dr Pääbo and his colleagues compared their pieces with the human genome, which has been fully
sequenced. By mapping stretches of Neanderthal DNA to its human equivalent, the researchers were able
to complete bits of the jigsaw.
Dr Rubin and his colleagues used what is called a “metagenomic?approach. This has one great
advantage it can be used to target specific areas of interest. The researchers propagated individual DNA
