Try it risk-free for 30 days

About This Chapter

The Processes and Steps of DNA Replication chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about DNA replication. These simple and fun video lessons are each about five minutes long, and they teach all of the processes and steps in DNA replication required in a typical MCAT prep course.

How it works:

  • Begin your assignment or other MCAT prep work.
  • Identify the DNA replication concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our MCAT tutoring solution will benefit any student who is trying to learn the processes and steps in DNA replication and prepare for the exam. This resource can help students including those who:

  • Struggle with understanding conservative and semi-conservative models, leading strand or any other DNA replication topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their MCAT prep unit on DNA replication steps and processes
  • Cope with ADD or ADHD
  • Want to get ahead in preparing for the MCAT
  • Don't have access to their MCAT instructor outside of class

Why it works:

  • Engaging Tutors: We make learning about DNA replication simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live MCAT tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about the processes and steps in DNA replication on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives:

  • Explore conservative, semi-conservative and dispersive models of DNA replication.
  • Examine how the DNA helicase unwinds the double helix in preparation for replication.
  • Learn how DNA polymerase and RNA primase initiate DNA replication.
  • Find out the significance of leading and lagging strands of DNA.
  • Review enzymes and replication bubbles.

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

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

DNA replication, the process of copying DNA, has three different models to explain its processes, the most well-known of which is the Meselson and Stahl model. Learn about their experiments, as well as how those experiments disproved older models.
How Helicase Unwinds the DNA Double Helix in Preparation for Replication

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

DNA helicase is a vital enzyme that unwinds the DNA double helix and prepares DNA for replication. Learn about this process by exploring the semi-conservative model of DNA replication, explore how DNA helicase unwinds the DNA double helix, and discover the origin of replication and replication fork.
How DNA Polymerase and RNA Primase Initiate DNA Replication

3. How DNA Polymerase and RNA Primase Initiate DNA Replication

DNA replication involves the process of splitting DNA molecules down the middle. Different enzymes, such as DNA polymerase and RNA primase, have different roles in this process, including building daughter strands of DNA and priming for replication. Learn about how DNA replication is started and the enzymes that help it occur.
DNA Replication: The Leading Strand and DNA Polymerase Activities

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

The beginning of DNA replication requires the splitting of two parent DNA strands. DNA polymerase makes short lengths of DNA that are then bound together by DNA ligase. Learn how these enzymes work together to aid in DNA replication.
DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

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

Enzymes, parent strands, and daughter strands are parts of the process of DNA replication. Learn about the parts of DNA replication, including enzymes, replication bubbles, and leading and lagging strands.
Examples of Transcription Regulation in Eukaryotes

6. Examples of Transcription Regulation in Eukaryotes

Transcription, or gene expression, in eukaryotic cells is regulated by DNA regulatory regions, DNA methylation, and chromatin modifications. Learn about transcription and real-world examples of transcription regulation in eukaryotic cells.
