Today, it is technically possible to sequence the 2.4 meters of DNA –&#160;present in the nucleus of every cell of our body – in only a few days. And, just as the speed of reliable sequencing continues to increase, the price of sequencing has dropped precipitously, and will soon amount to just a few hundred dollars.
如今，我们已能在技术上测定2.4米长的DNA序列——在我们体内的每一个细胞内都有这样一套DNA，而且只需要花费几天时间。此外，不但可靠测序的速度在持续加快，测序的价格在迅速下降，很快就会低到几百美元的水平。一旦我们获知每个DNA片段的功能，常规测序之路就能畅行无阻了。
