Boolean calculations made easy (for ribozymes)

Article Abstract:

A study describes a precise protocol to construct and test a complete set of ribozyme-based logic gates whose self-cleavage activity is modulated by the presence of oligonucleotide inputs. The work also gives some idea of how these elementary units can be organized into more complex circuits.
