By engineering new genetic codes we can:
• produce organisms immune to viruses
• make universal systems for “plug and play” with new amino acids
new roomfor plug &
play
• block exchange of genes, a “genetic firewall”

Multiplex Automated Genome Engineering (MAGE)
“Find and replace” with
the DNA of the genome
![Page 8: SS -1 PAC 8/18/11 Recoding the Genome Peter Carr 18 August 2011 FAB7 Lima, Peru](https://reader033.vdocuments.mx/reader033/viewer/2022051618/56649d2c5503460f94a0215d/html5/thumbnails/8.jpg)
SS -8PAC 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.
