Ch 7: DNA Replication: Biology 101 Lesson Plans

About This Chapter

The DNA Replication chapter of this course is designed to help you plan and teach the semi-conservative model of DNA replication in your classroom. The video lessons, quizzes and transcripts can easily be adapted to provide your lesson plans with engaging and dynamic educational content. Make planning your course easier by using our syllabus as a guide.

Weekly Syllabus

Below is a sample breakdown of the DNA Replication chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.

Day Topics Key Terms and Concepts Covered
Monday Models of DNA replication Experiments proving or disproving the semi-conservative, conservative and dispersive models of DNA replication
Tuesday DNA helicase DNA helicase's role in separating the parental and daughter strands of DNA to prepare for replication
Wednesday DNA polymerase and RNA primase RNA primase and the synthesis of RNA primer; DNA polymerase and the addition of daughter nucleotides
Thursday Leading and lagging strands Continuous and discontinous replication; the function of DNA ligase in joining together Okazaki fragments
Friday DNA replication review An overview of the roles DNA helicase, RNA primase, DNA polymerase and DNA ligase play in the replication process

5 Lessons in Chapter 7: DNA Replication: Biology 101 Lesson Plans
What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

1. What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

How do we know that DNA replication is semi-conservative? How do we know it's not conservative or dispersive? Let's follow the famous experiment by Meselson and Stahl to find out!

How Helicase Unwinds the DNA Double Helix in Preparation for Replication

2. How Helicase Unwinds the DNA Double Helix in Preparation for Replication

How does semi-conservative replication begin? Discover how DNA helicase creates a replication fork to unwind the complicated DNA molecule and allow daughter strands to form on the parental template.

How DNA Polymerase and RNA Primase Initiate DNA Replication

3. How DNA Polymerase and RNA Primase Initiate DNA Replication

How do enzymes assist in starting DNA replication? In this lesson, we explore the work of a contributing enzyme, DNA polymerase, and learn how the RNA primer is made by the action of RNA primase.

DNA Replication: The Leading Strand and DNA Polymerase Activities

4. DNA Replication: The Leading Strand and DNA Polymerase Activities

How does replication occur in the antiparallel DNA molecule? In this lesson, explore the significance of the leading and lagging strands, and learn how Okazaki fragments and RNA ligase make DNA replication possible.

DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

5. DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

Feeling lost in the thorny details of DNA replication? This lesson provides an overview of semi-conservative replication, with a focus on putting together all of the concepts involved. We'll review the work of each enzyme on our way to completing the big picture of DNA replication.
