CEOE Middle Level Science: DNA Replication - Chapter Summary

Studying for your certification test doesn't have to be a chore. By reviewing the lessons in this chapter, you can simplify the process of preparing for the CEOE Middle Level Science assessment by refreshing your knowledge of DNA replication. In no time, you will be ready for the following on the exam:

  • Defining DNA replication and discussing conservative, semi-conservative and dispersive models
  • Explaining how DNA helicase unwinds the double helix for replication
  • Describing the roles of DNA polymerase and RNA primase in DNA replication
  • Discussing the leading strand and DNA polymerase activities of DNA replication
  • Providing details about enzymes, replication bubbles, and lagging and leading strands

The resources in this chapter help you avoid the challenging process of compiling study materials for the exam. Instead, you can kick back and watch fun and engaging videos designed to boost your comprehension of DNA replication. Before, during or after reviewing the lessons, take self-assessment quizzes to test your knowledge. If you have any questions about lesson topics, feel free to submit them to our experts.

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.
