DNA's Error Detecting Code

MagnetarJones writes "Science News Online and Nature.com - Genetic information stored in DNA is read out - transcribed - every time living cells make a new protein molecule to perform some cell function. And this information is copied onto a new strand of DNA when a cell divides. The consequences of wrongly read or copied information can be disastrous. Malfunctioning genes can cause diseases and defects. Errors can occasionally have beneficial effects - they create the mutations that drive the evolutionary process - but they are usually detrimental. Strands of DNA carry information--of the genetic sort--encoded in their chemical structure. Chemist Dónall A. Mac Dónaill of Trinity College in Dublin, Ireland, has now shown that patterns inherent in the chemical makeup of DNA correspond to a digital error-detecting code. His report appears in the Sept. 12 Chemical Communications."
