Shipud writes: A group from Oak Ridge National Laboratory, Yale University and the Joint Genome Institute have isolated single cells of otherwise elusive and unculturable SR1 bacteria and sequenced their genomes. They found that SR1 deviate from the genetic code in a way previously unknown: what codes for "stop making proteins" in most organisms, is used differently in SR1, to actually continue making them. This study shows the power of a new technology, single-cell DNA sequencing, to reveal genetic information. SR1 bacteria are found in our mouths, and are suspected to cause periodontitis.
