DNA polymerases are the "Xerox machines" that replicate our DNA. They must work with great precision to preserve errors from creeping into our genes. In spite of this precision,they still accept building blocks that have been coupled to large proteins, as a group of German scientists reports in the journal Angewandte Chemie. Based on this fact, and the team has developed detection systems for genotyping DNA and RNA that can be evaluated by the bare eye. This method may allow for new diagnostic tools for exercise in the field.
