About This Chapter
Below is a sample breakdown of the Genetic Mutations chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Different types of mutation||Mutation, point mutations, substitutions, transversions, insertions, transitions, deletions, and DNA sequence|
|Tuesday||How mutations affect protein functions||Missense mutation, silent mutation, and nonsense mutation|
|Wednesday||The environment's effect on mutation||Mutagens, DNA polymerase, and base substitutions|
|Thursday||What are frameshift mutations?||Reading frame, codon, frameshift, and causes of frameshift mutations|
|Friday||Mutations in our world||Tay-Sachs disease, Duchenne muscular dystrophy (DMD), sickle cell anemia, color blindness, advantageous mutations, and genetic diversity|
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.
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.
3. 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.
4. 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.
