Ch 32: MTEL Biology: DNA Replication

About This Chapter

We can show you the main and supporting ideas about DNA replication. These video lessons and self-assessment quizzes give you a variety of ways to learn the material, so that you can correctly answer questions on these topics on the MTEL Biology exam.

MTEL Biology: DNA Replication - Chapter Summary

The lessons found in this chapter can help you learn all the important points about DNA replication that you will need to know for the MTEL Biology exam. The videos cover all the topics and can help you with these types of questions on the test:

  • DNA replication
  • The role of helicase
  • DNA polymerase and RNA primase
  • The leading strand and DNA polymerase activities
  • Enzymes, replication bubbles, and leading and lagging strands

Our experienced instructors take you through each topic, explaining it thoroughly and highlighting the key concepts and terms, to help you prepare for the test. By having several approaches you can use to learn the material, you are able to learn it more efficiently and effectively.

Objectives of the MTEL Biology: DNA Replication Chapter

The MTEL Biology exam is a test with two basic parts to it: multiple-choice, and open-response. The multiple-choice section counts for 80% of your grade with 20% from the open-response. The exam evaluates the depth and breadth of your knowledge of biology. The score is used to determine if you should be licensed as a teacher in the Commonwealth of Massachusetts. The topics in this DNA Replication chapter is part of the Genetics, Evolution and Biodiversity objective of the exam. There will be 17-19 multiple-choice questions on this objective. By completing the self-assessment quizzes that come with each video lesson, you can measure your mastery of the material and gain experience answering the kinds of questions you will face on the actual test.

There are 100 multiple-choice items on the test. Each asks you to read a passage or questions and then pick the correct answer from the choices displayed. There are two open-response items. You will be asked to write two essays demonstrating your understanding of biology topics and your ability to compose a well organized, logical and articulate narrative.

Test your knowledge with a 30-question chapter practice test
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.
