Ch 4: DNA Replication & Mutation: Help and Review

About This Chapter

The DNA Replication and Mutation chapter of this Middle School Life Science Help and Review course is the simplest way to master the process of DNA replication and mutation. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of DNA replication and mutation.

Who's it for?

Anyone who needs help understanding middle school life science material will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn better grades. You're in the right place if you:

  • Have fallen behind in understanding enzymes or DNA replication and mutation.
  • Need an efficient way to learn about DNA replication and mutation.
  • Learn best with engaging auditory and visual tools.
  • Struggle with learning disabilities or learning differences, including autism and ADHD.
  • Experience difficulty understanding your teachers.
  • Missed class time and need to catch up.
  • Can't access extra science learning resources at school.

How it works:

  • Start at the beginning, or identify the topics that you need help with.
  • Watch and learn from fun videos, reviewing as needed.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Submit questions to one of our instructors for personalized support if you need extra help.

8 Lessons in Chapter 4: DNA Replication & Mutation: Help and Review
Function of Enzymes: Substrate, Active Site & Activation Energy

1. Function of Enzymes: Substrate, Active Site & Activation Energy

In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!

Aneuploidy & Polyploidy: Definition & Examples

2. Aneuploidy & Polyploidy: Definition & Examples

We are going to cover the terms ploidy, aneuploidy and polyploidy in this lesson. We'll also explain how each of these occur and get examples of each.

Pros & Cons of Cloning

3. Pros & Cons of Cloning

In this lesson, we'll explore the major pros and cons of cloning. Before we get into the meat of the lesson, we'll review what cloning is, and then we will look at examples of how cloning could benefit society and some reasons we might need to hold off.

Animal Cloning: Definition, Examples & Extinct Animals

4. Animal Cloning: Definition, Examples & Extinct Animals

Did you know there are clones all around us? That's something many people don't realize. So what exactly are clones? This lesson investigates cloning, types of clones, and cloning's connection to extinct animals.

Animal Cloning: Pros & Cons

5. Animal Cloning: Pros & Cons

In this lesson we'll be learning about the benefits and challenges of animal cloning. Here we'll review what cloning is, animals that have been currently cloned, and applications. Then we'll look at cautions and challenges of animal cloning.

History of Cloning Animals

6. History of Cloning Animals

Animal cloning is one of the most fascinating topics in biology. This lesson covers the history of cloning, from the first animal cloned over 100 years ago up to the most recent developments in genetic engineering.

Infectious Diseases: Definition & Types

7. Infectious Diseases: Definition & Types

Infectious diseases can be as mild as the flu or as deadly as Ebola. In this lesson, you'll learn about infectious diseases: what they are, some examples of common ones, and how to prevent and treat them.

Non-Infectious Diseases: Definition & Examples

8. Non-Infectious Diseases: Definition & Examples

Not all diseases can be spread from one person to another. In this lesson, we'll learn about non-infectious diseases: what they are, some examples of them, and how they are treated.
