The aim of the experiment is to perform gel electrophoresis for the two PCR reactions Pspac_oid promoter amplified from plasmid pMutin4 and from plasmid pMK-RQ containing Biobrick ''kinA'' and plasmid pMK-RQ containing stochastic switch developed by Team Newcastle 2009 which took place today morning and thus confirm that they were successful.

'''Table 3''': Table represents the size of the Pspac_oid fragment represented as bands on the gel in all the lanes.
+
-
 
+
-
==Discussion==
+
-
We found two bands in the all lanes out of which one is of approximately of 150 bp is size and the other band is of 80 bp approximately in size.
+
-
 
+
-
==Conclusion==
+
-
This experiment shows that the PCR reaction was not perfectly successful for the Pspac_oid fragment. The problem is that there are 2 fragments on the gel instead of 1 and the second band which of 80bp in size might be corresponding to primer dimers. When we checked the primer sequence again, we found that there is a high complementarity within the primers itself and thus the amplification of the Pspac_oid fragment is not taking place at a desired rate. The first band present on the gel can be of the Pspac_oid fragment and thus tomorrow 10th August, 2010, we would be doing gel extraction for the fragment and will check whether these fragments are of Pspac_oid or not.
