Digital DNA Circuits

Posted by michael on Tuesday April 29, 2003 @07:55AM from the synergistic-merger dept.

TheSync writes "ScienceNews has a story about digital DNA circuits. The circuits use proteins that activate or deactivate genes on the DNA for control. Since an inverter and an AND gate have been created, any digital logic circuit can now be done in DNA. Moreover, evolution can help make circuit elements work better. There is even a "databook" of BioBricks circuit elements and BioSPICE for biocircuit simulation."

Transcription and translation happen at about 45 nucleotides per second in bacteria, meaning it takes at least a few seconds to get a signal through a genetic "gate" or "switch".
