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.

Mutagens: How the Environment Affects Mutation Rates

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.

Effects of Frameshift Mutations: Definitions and Examples

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.

Missense Mutation: Definition & Example

5. Missense Mutation: Definition & Example

While people with sickle-cell disease show many symptoms, such as pain and fatigue, this disease is caused by only a single change in a DNA sequence. You can learn more about this kind of change, called a missense mutation, in this lesson.
