Schedule of Experiments
Lab # | Dates | Activity | Outside lab time |
---|---|---|---|
5 | 10/5 - 10/12 | Pick a gene of interest Set up a PCR reaction to clone the gene |
Examine the results of the agarose gel electrophoresis |
6 | 10/13 - 10/19 | Restriction enzyme digest of PCR product Cleanup and ligation into the pPD129.36 vector |
The day after lab: Check control and transformation plates for growth - save your transformation plate |
7 | 10/20 - 10/26 | Colony PCR to check for transformation | The night before next lab: Set up an overnight culture of a single colony from your transformation |
8 | 10/28 - 11/3 | Plasmid isolation from the BL21 cells Quantification of DNA |
The day after lab: Check control and transformation plates for growth - save your transformation plate |
9 | 11/4 - 11/10 | Induction of the bacteria to produce RNA Seed plates and dry for bacterial feeding RNAi |
4 days later: Pick 2 L4 hermaphrodite worms of N2 and rrf-3 genotype to 2 RNAi plates for each genotype and make 1 control "mock" plate for each genotype as well (6 plates total) |
10 | 11/11 - 11/17 | Examine the phenotypes of the fed worms - compare to control N2 worms and worms containing a mutation in the gene you are examining Collection of treated worms and RNA purification |
|
11 | 11/29 - 12/3 | Reverse transcription and PCR reactions Instructors run gels |
Review and interpret the resulting gel images |
