Solexa, based in Hayward, Calif., is one of several companies trying to develop methods to determine the sequence of DNA in an organism at less cost and far more quickly than the technology used only a few years ago in the Human Genome Project.That is amazing that the price is already down to $100,000. I wonder what the Moore's law of DNA sequencing looks like.
Eventually DNA sequencing might be so cheap that every person would be able to carry around his or her complete genetic blueprint on a DVD or computer chip.
That day is still far in the future. But Solexa is expected to soon begin shipping a DNA sequencing machine that it claims will be able to determine the three billion DNA units in a person’s genome for about $100,000, about one-hundredth the cost of using older sequencers.
The thing I have never understood is that the human genome is just one copy of 23 chromosomes while each person has 2 copies. When you are getting your own genome sequenced, I would assume you would do it for both copies. I believe that would be 6 billion DNA units. So, wouldn't having your "genome" sequenced really cost twice as much or $200,000? If anyone knows the answer, please leave a comment.
