SS -6 PAC 8/18/11 By engineering new genetic codes we can: produce organisms immune to viruses make universal systems for “plug and play” with new amino acids new room for plug & play block exchange of genes, a “genetic firewall” rearrange to block function Second Position

SS -7 PAC 8/18/11 Multiplex Automated Genome Engineering (MAGE) “Find and replace” with the DNA of the genome

SS -8 PAC 8/18/11 Key features of MAGE: Multiplexed: can address many sites at once Targeted: modifies specific sequences; changes made can be specific or random Iterated: weak efficiency can be compensated by automating many cycles of modification Tunable: can control the range of diversity generated in a population Clean: no DNA scars, no resistance gene markers, etc.
