Read the original 1998 paper by Fire and Mello published in Nature 391: 806-811 (Feb.19 1998); Do your own library search to find and read a recent review article about RNAi in C. elegans. Also read the 2002 Simmer et al. paper in Current Biology 12:1317-1319 explaining the rrf-3 strain that we will use for our RNAi work. These articles provide background information on how the mechanism of RNAi was worked out experimentally and will be helpful to you when you write the introduction section of your Series3 paper. Also read a published journal article by Green et al. (2009) Impact of Cigarette Smoke Exposure on Innate Immunity: A Caenorhabditis elegans Model PLoS ONE 4(8): e6860. This study, like yours, uses reverse genetics to investigate gene function.
