Students will review:
This chapter helps students review the concepts in the DNA replication unit of a standard high school chemistry course. Topics covered include:
- What is DNA replication?
- Models of DNA replication
- Role of DNA polymerase and RNA primase
- Replication bubbles
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.
6. What is the Difference Between Chemistry & Physics?
Chemistry and physics are both physical sciences and are both interested in the structure of matter. However, they also have a great deal of differences. In this lesson, we'll compare and contrast the fields of chemistry and physics.
7. What is Analytical Chemistry? - Definition & Impact
In this lesson we will learn about analytical chemistry. We will look at the history of this branch of science, explore what analytical chemists do, and see how it has impacted the world around us.
8. Analytical Chemistry: Techniques & Methods
In this lesson we will learn about analytical chemistry. We will describe some common methods and techniques that are used in analytical chemistry, including wet chemistry and instruments used.
9. Analytical Chemistry: Instruments & Equipment
This lesson will focus on the types of instrumentation and equipment that analytical chemists use to test the purity of compounds and separate the individual compounds that make up a mixture.
10. What is Physical Organic Chemistry?
Sometimes scientists use what they know about physical chemistry to study how organic molecules behave. Such scientists often belong to a scientific discipline called physical organic chemistry. In this lesson, discover and learn more about this emerging field.
11. What is Environmental Chemistry? - Topics & Definition
This lesson teaches you about the topic and importance of environmental chemistry. Find out what people in this field do and how it impacts the environment around us.
12. What is Quantum Chemistry?
In this lesson, we will get a brief overview of quantum chemistry, a sub-discipline of chemistry that focuses on the properties and behavior of subatomic particles, especially electrons. Without a foundational understanding of electron behavior, it would be impossible to understand the concepts of chemical bonding.
