| - | ==Materials and Protocol==
| + | The aim of this experiment is to set up cultures for minipreps to obtain stock of the filamentous cell part in pGFP-rrnB for transformation into ''Bacillus subtilis'' 168. We selected 12 colonies for screening. |

| - | ==Discussion==
| + | |
| - | No bands were found in any of the lanes. Yesterday, a faint band was found when the melting temperature was set at 65°C but today no band is found in lane 3 and lane 7. This makes finding the cause for no amplification even difficult. We would still be looking into it and would be changing other parameters.

| - | | + | |
| - | ==Conclusion==
| + | |
| - | The PCR reaction failed as there is no amplification found in any of the reactions.

| - | ==Aims==
| + | |
| - | The aim of this experiment is to run gel electrophoresis for the extracted and linearized plasmid pSB1C3 fragment which were amplified at 4 different melting temperatures by 4 separate PCR reactions and to put Ethidium Bromoide (EtBr) in the agarose gel instead of safeview die so as to get better resolution and brighter bands.

| |
| - | Please note that in this protocol we have made a minor modification which is that instead of adding 5µl of safeview dye, we have added 5µl of EtBr into the agarose gel so as to get better resolution and brighter bands.
