Ch 6: DNA Mutations: Help and Review

About This Chapter

The DNA Mutations chapter of this Intro to Anthropology Help and Review course is the simplest way to master an understanding of DNA damage and mutations. 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 mutations.

Who's it for?

Anyone who needs help learning or mastering introductory anthropology material will benefit from taking this course. There is no faster or easier way to learn introductory anthropology. Among those who would benefit are:

  • Students who have fallen behind in understanding mutagens or DNA mutations
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning social science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about DNA mutations
  • Students who struggle to understand their teachers
  • Students who attend schools without extra social science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the DNA Mutations chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the DNA Mutations chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any DNA mutations question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a DNA mutations unit of a standard general anthropology course. Topics covered include:

  • Effects of mutations on protein function
  • Mutagens
  • Causes of mutation and DNA damage
  • DNA mismatch repair
  • Reversing DNA damage caused by irradiation and mutagens

11 Lessons in Chapter 6: DNA Mutations: Help and Review
What is a Point Mutation? - Definition, Causes & Types

1. What is a Point Mutation? - Definition, Causes & Types

What are genetic mutations? How do they affect our DNA? This lesson covers the basics of point mutations and provides simple examples of different mutation types.

Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations

2. Effects of Mutations on Protein Function: Missense, Nonsense, and Silent Mutations

How does a tiny point mutation change the way a protein works? What are the consequences of base substitutions? In this lesson, we'll use an imaginary creature to explore missense, nonsense and silent mutations.

Effects of Frameshift Mutations: Definitions and Examples

3. Effects of Frameshift Mutations: Definitions and Examples

What is a frameshift in genetic translation? How can a frameshift mutation change a protein? In this lesson, learn about the codon reading frame and how frameshift mutations cause serious problems for polypeptide formation.

Mutagens: How the Environment Affects Mutation Rates

4. Mutagens: How the Environment Affects Mutation Rates

What causes mutations to occur in living things? How do we avoid mutations? Are mutations always bad? Discover answers to these questions and more in this lesson on mutagens.

Causes of Mutation and DNA Damage- Mutagens

5. Causes of Mutation and DNA Damage- Mutagens

Mutations, or changes in DNA sequences, are incredibly important in biology, from evolution and diversity to cancer and genetic diseases. But how do mutations happen? In this lesson, you'll learn about mutagens, which are chemicals that can cause mutations.

Causes of Mutation and DNA Damage- Irradiation

6. Causes of Mutation and DNA Damage- Irradiation

By now, you know what mutations are and what effects they can cause, but how do mutations happen? In this lesson, learn about one important cause of mutations, irradiation.

DNA Mismatch Repair: Correcting Errors That Happen During DNA Replication

7. DNA Mismatch Repair: Correcting Errors That Happen During DNA Replication

Don't you love spell check? Well, our cells do, too. Their spell check is called mismatch repair. In this lesson, learn how cells use mismatch repair to correct typos that they might make while they replicate their DNA.

Reversing DNA Damage Caused by Mutagens and Irradiation

8. Reversing DNA Damage Caused by Mutagens and Irradiation

Nobody likes to have surgery, but sometimes it's necessary to cut out the bad parts and replace them with fresh new tissue. The same is true for DNA! In this lesson, learn how DNA damage can be repaired in both surgical and non-surgical ways.

DNA Repair: Fixing Double-Strand Breaks

9. DNA Repair: Fixing Double-Strand Breaks

'Humpty Dumpty sat on a wall...' We all know what happens next, right? In this lesson, learn what happens when DNA is broken into pieces and how our cells try to put them back together again.

Deletion Mutation: Definition, Examples & Diseases

10. Deletion Mutation: Definition, Examples & Diseases

Mutations are errors in the replication of DNA. Sometimes a piece of DNA can be deleted from the copy, creating a devastating effect on the organism's ability to manufacture an important protein. This can lead to disease.

Wild Type in Genetics: Definition & Traits

11. Wild Type in Genetics: Definition & Traits

Identifying the genetic 'wild type' in populations is critical to understanding how that population is changing. Here we will define the 'wild type' and review some examples. At the end, you can test your knowledge with a short quiz.
