About This Chapter
NYSTCE Biology: DNA Replication - Chapter Summary
You will use the lessons in this chapter to reinforce your knowledge of the types of DNA replication and to define terms used in these processes. The lessons cover the following topics to help you answer relevant questions found on the Biology CST:
- Reviewing DNA replication processes
- Describing how DNA prepares for replication
- Discussing how DNA replication is initiated
- Identifying the DNA strands and fragments that play a role in replication
- Summarizing the enzymes activated during the DNA replication process
The video lessons are particularly helpful to those who find visual learning most effective when studying biology topics. Taking the short quizzes found at the end of each lesson is a great way to see what you have retained from watching the lessons.
NYSTCE Biology: DNA Replication Chapter Objectives
By reviewing the material presented in the DNA Replication chapter, you will be better prepared to answer questions in the Cell Biology and Biochemistry subarea of the Biology CST that focuses on understanding DNA and RNA structures and functions. This section accounts for 17% of the score. The test is comprised of 90 multiple-choice questions and a written assignment. The test is computer-based.
The NYSTCE (New York State Teacher Certification Examinations) are used to certify teachers in areas of teaching practice and knowledge. In addition to specific content areas, teachers can seek certification in literacy skills, teacher performance, elementary and secondary teaching skills, bilingual assessment, and communication skills.
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!
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.
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.
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.
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.
