My colleagues and I are exploring this within E. coli, the microbial powerhouse of the biotech world. By simply changing a certain 314 of the 5 million bases in the E. coli genome, we can change one of its 64 codons.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://seedmagazine.com/content/article/safeguarding_biology/P2/"><div align="center"><img src="http://content6.clipmarks.com/blog_cache/seedmagazine.com/img/6FDE2395-6F92-490B-A24D-71E760F190DD" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://seedmagazine.com/content/article/safeguarding_biology/P2/">GEOs could take over ecosystems. This might be handled by making engineered cells dependent on nutritional components absent from natural environments. For example, we can delete the genes required to make diaminopimelate, an organic compound that is essential for bacterial cell walls (and hence bacterial survival) yet very rare in humans and our environment</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/3B7ACB1C-D599-433C-8502-CA53C38BBBFF/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
