===Project Description===
 
-
The purpose of this subproject is to make the nah operon biobrick compatible for the use of future iGEM teams. The nah operon is an operon that converts napthalene into salicylate. In our system, this will allow napthalene to be detected by the salicylate reporter. There are three standard cutsites internal to the operon which we are removing - the biobrick compatible piece could be used by future teams in bioremediation projects.

-
:Set up [http://2011.igem.org/Team:Cornell/Protocols PCR] for four fragments of the nah operon as well as the pBMT-1 backbone, using primers designed to mutate cut-sites concurrently with Gibson Assembly. Also set up a PCR for the entire nah operon. Due to length of the fragments, a longer extension time was chosen.
 
-
:If Gibson Assembly fails, but we are able to PCR the entire 10kb nah operon using Phusion polymerase, an alternate method of mutation using Phusion will be pursued.

-
:PCR only amplified nah1, nah3, and nah4 - longer fragments (nah2, the full nah operon, and pBMT-1) were not identified on the PCR product gel. Set up another [http://2011.igem.org/Team:Cornell/Protocols PCR] with shorter extension time.

-
:PCR of four out of five products visible on gel. Set up PCR of pBMT-1, final fragment required for Gibson Assembly of the nah operon.

:Ran Gibson Assembly of nah operon fragments into pBMT-1 backbone and transformed into DH5a electrocompotent ''E. coli'' cells.
 
-
:Set up [http://2011.igem.org/Team:Cornell/Protocols PCR] to amplify the Gibson Assembly products.

-
:Set up a [http://2011.igem.org/Team:Cornell/Protocols digestion] of the PCR of Gibson Assembly products and ran the digested products on a gel to see if Gibson worked.
 
-
:We'll also check to see if we got colonies from the transformation then.
