Schedule of Experiments

Lab #	Dates	Activity	Outside lab time
5	9/29 - 10/5	Pick a gene of interest Set up a PCR reaction to clone the gene	Examine the results of the agarose gel electrophoresis
6	10/12 - 10/18	Restriction enzyme digest of PCR product Cleanup and ligation into the pPD129.36 vector Transformation of the isolated plasmid into the BL21 cloning E. coli	The day after lab: Check control and transformation plates for growth - save your transformation plate
7	10/19 - 10/25	Colony PCR to check for transformation	The night before next lab: Set up an overnight culture of a single colony from your transformation
8	11/2 - 11/8	Plasmid isolation from the BL21 cells Quantification of DNA Transformation of plasmid into the HT115(DE3) cells	The day after lab: Check control and transformation plates for growth - save your transformation plate The night before next lab: Set up an overnight culture of a single colony from your transformation
9	11/9 - 11/15	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) Incubate at 23°C until next class
10	11/16 - 11/22	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	11/28 - 12/2	Sign up for a time to meet and discuss your final paper draft with your instructor - we will not meet in lab this week.
