Chapter 14.2, Problem 3C
Summary Introduction
To explain: The reasons why trp operon is repressible and lac operon is inducible.
Introduction: Operons are a set of genes containing a promoter and one or more operators that helps to control the transcription process. Each operon is made of structural genes, promoter and operator. Inducible operons are turned on by the presence of the substrate. Lac operon is an inducible operon. Repressible operons are turned off by the presence of the substrate. Trp operon is a repressible operon.

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
