About This Chapter

The DNA Replication - Processes and Steps chapter of this High School Biology Homework Help course helps students complete their DNA replication processes and steps homework and earn better grades. This homework help resource uses simple and fun videos that are about five minutes long.

How it works:

  • Identify which concepts are covered on your DNA replication processes and steps homework.
  • Find videos on those topics within this chapter.
  • Watch fun videos, pausing and reviewing as needed.
  • Complete sample questions and get instant feedback.
  • Finish your DNA replication processes and steps homework with ease!

Topics from your homework you'll be able to complete:

  • Conservative, semi-conservative and dispersive models of DNA replication
  • Role of helicase and the DNA double helix in replication
  • DNA polymerase and RNA primase
  • The leading strand and DNA polymerase activities
  • Enzymes, replication bubbles and leading & lagging strands

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.
