Ch 11: Holt McDougal Modern Biology Chapter 11: Gene Expression

About This Chapter

The Gene Expression chapter of this Holt McDougal Modern Biology textbook companion course helps students learn essential modern biology lessons on gene expression. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Gene Expression textbook chapter.

How it works:

  • Identify the lessons in the Holt McDougal Modern Biology Gene Expression chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the gene expression topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Regulation of gene expression
  • Operon control of transcription in prokaryotic cells
  • RNA processing in eukaryotic cells
  • Cell differentiation and morphogenesis
  • Causes of cancer
  • Cancer at the genome level
  • Metastasis

Regulation of Gene Expression: Transcriptional Repression and Induction

1. 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.

How An Operon Controls Transcription in a Prokaryotic Cell

2. 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.

What Is Cell Differentiation? - Process, Importance & Examples

3. What Is Cell Differentiation? - Process, Importance & Examples

In this lesson, you will learn how your cells become specialized. This specialization of cells allows them to perform different functions and create different parts of your body.

RNA Processing in a Eukaryotic Cell: Splicing of Introns & Exons

4. 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.

What Causes Cancer?

5. What Causes Cancer?

This lesson will discuss a model of cancer formation as well as some things that can cause cancer. You'll learn about initiation, promotion, and progression as well as what occurs during each step.

Cancer at the Level of the Genome

6. Cancer at the Level of the Genome

This lesson will delve into the genetic changes that may occur during cancer formation. You'll learn about proto-oncogenes, oncogenes, tumor suppressor genes, viral oncogenesis, p53, and more.

Metastasis: How Cancer Spreads

7. Metastasis: How Cancer Spreads

This lesson will describe the concept of cancer spreading around the body, or metastasis, as well as why it may occur, how it occurs, why it may fail, and how your blood vessels play a critical role in this process.
