About This Chapter
Gene Structure & Regulation - Chapter Summary
Instructors in this chapter have developed fun lessons you can use to strengthen your knowledge of gene structure and regulation. Use this chapter to study topics that include the regulation of gene expression and the RNA processing in a eukaryotic cell. When finished, you will be ready to do the following:
- Describe the functional differences of structural and regulatory genes
- Explain how repression and induction are used to regulate gene expression
- Discuss the splicing of introns and exons as it relates to RNA processing in a eukaryotic cell
- Detail how transcription in a prokaryotic cell is controlled by an operon
Around-the-clock accessibility and mobile features enable you to review this chapter's lessons anytime using any tablet, smartphone or computer with an Internet connection. Feel free to navigate the lessons in sequence or review only the lessons you need to better understand in any order you desire. Find out how much you understand about gene structure and regulation by taking multiple-choice quizzes and a chapter exam. Any questions you have about this chapter's topics can be submitted to our experts.
1. Functional Differences of Structural & Regulatory Genes
In this lesson, we'll be exploring the differences between structural and regulatory genes. We'll explain what each type of gene is and look at examples in the human body.
2. Regulation of Gene Expression: Transcriptional Repression and Induction
Do our genes work the same way all the time? How do we regulate the expression of our genes? Explore the various ways organisms control gene transcription through repression and induction of operons.
3. RNA Processing in a Eukaryotic Cell: Splicing of Introns & Exons
In this lesson, we'll explore the unique considerations for gene regulation in the eukaryotic cell. We'll walk through RNA splicing of introns and exons and the addition of the 5' cap and poly(A) tail.
4. How An Operon Controls Transcription in a Prokaryotic Cell
Is gene regulation really as simple as flipping a switch? What are the parts of an operon, and how do they function to control gene transcription? We'll study the lac operon to answer these questions.
