- Chrsitine did more minipreps for colonies suspected of containing the 7 gene operon. When these minipreps were run on a gel there was no evidence of an insert.

- Christine cloned (*a→g*) into TOPO vectors using different ratios of PCR product:TOPO vector (see Protocol 12 ). Ratios were 0.5ul:1ul, 1ul:1ul, and 2ul:1ul.
- TOPO vectors with different ratios of PCR product:TOPO vector were tranformed (see Protocol 13 (with 30 sec heat shock at 42°C and 250ul of 37°C LB instead of SOC medium))and grown overnight on kanamycin plates at 37°C, each reaction divided into 100ul and ~200ul per plate.

Maija digested the construction vectors 3/20G and 4/6B, and the 7 gene operon with SpeI and XbaI (Protocol 7) with the intention of then ligating the 7 gene operon into the construction vectors. The 7 gene operon DNA (taken from sample 2 of the PCR which was gel extracted 13/08/07) did not appear on the gel.

Christine gel extracted 4/6B and 3/20G (see Protocol 11) using 30ul ddH2O at 60°C to elute the DNA.
