Advanced For experienced high school and college classes; requires some technical skill.
- Demonstrate to your students the power of silencing a single gene.
- Teach about a powerful method for determining gene function.
- Introduce your students to a model organism used for studying many aspects of biology, including development and gene function.
- Engage in bioinformatics exercises exploring protein function and C. elegans and human gene relatedness.
In this lab, wild-type worms are fed lab strains of E. coli that express double-stranded RNA (dsRNA) corresponding to either of 2 target genes: BLIstered cuticle (bli-1)
or DumPY (dpy-11)
. The ingestion of the dsRNA initiates the destruction of mRNA expressed from the target genes. Students then examine the phenotypes induced by silencing these genes. Silencing bli-1
leads to the formation of clear blisters in a worm’s outer cuticle; silencing dpy-11
leads to a worm developing a short, fat body. In accompanying bioinformatics exercises, students explore the function of the protein encoded by the silenced gene and the relatedness of worm and human genes. Note: Order the kit with the perishable materials included (item #211391P) or with a prepaid coupon to request perishables later at your convenience (item #211391). Because of the time-sensitive preparation and limited shelf life of the kit’s perishable materials, please order a minimum of 2 weeks prior to the desired ship date.
