Series 3 Reverse Genetics: Scoring RNAi Worms

3 days before next lab:

  1. Come into lab and find your stack of plates.
  2. On 2 of the experimental plates add 2 L4 wild type (N2) hermaphrodites
  3. On 2 of the experimental plates add 2 L4 rrf-3 hermaphrodites
  4. On 1 of the control plates add 2 L4 wild type (N2) hermaphrodites
  5. On 1 of the control plates add 2 L4 rrf-3 hermaphrodites
  6. Wrap all of your plates in an elastic and stick in your lab day box in the worm incubator set at 23°C


Phenotypic Analysis

Today in lab you will examine your RNAi worms and their progeny.

  1. Examine worms with a known bli-1 mutation to see what knockdown looks like.
  2. Compare your RNAi worms to worms that have a known bli-1 mutation - how do they compare?
  3. Examine your control worms to review wild type phenotype in comparison to mutants
  4. Compare your RNAi worms to the control worms - are they the same phenotype? Different? What do the “control” worms tell you?
  5. Examine your RNAi’d wild type (N2) and then your RNAi’d rrf-3 worms. Do you see any differences between the two treated strains of worms?


Be sure to record all of your results in your lab notebook.
Take pictures of your control and RNAi worms to use in the results section of your next paper.
