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||How Point Mutations, Insertions and Deletions Affect DNA||Various kinds of mutation and their influence on DNA|
|Tuesday||How Point Mutations, Insertions and Deletions Affect DNA||Insertions, deletions, transversions and transitions|
|Wednesday||Effects of Mutations on Protein Function: Missense, Nonsense and Silent Mutations||Base substitutions and point mutations|
|Thursday||Effects of Frameshift Mutations||The definition and function of a frameshift mutation|
|Friday||Mutagens: How the Environment Affects Mutation Rates||The role of mutagens in mutations|
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.
