Question
Chapter 15.3, Problem 1C
Summary Introduction
To predict: The function of the gene in C. elegans that resulted in the inability of worm to touch when it is exposed to an RNAi molecule homologous to a non-protein-coding RNA gene.
Concept introduction: MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are non-coding RNA sequences that regulate the gene function and expression. They are approximately 20-30

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
