Ch 10: MTLE Life Science: Gene Mutation & Expression

About This Chapter

Read about how genetic material is structured and what happens when it changes in these lessons on genetic mutation and expression. Let these lessons provide you with information that will help you prepare for the MTLE Life Science test.

MTLE Life Science: Gene Mutation & Expression - Chapter Summary

This chapter discusses and explains how any change in the genetic material of a cell can impact the organism, and the factors that can cause or affect those changes. Upon completion of this chapter's lessons, you'll be well-prepared for any items on the MTLE Life Science test that deal with:

  • The composition and functions of genes
  • The impact of genetic mutations on DNA
  • Effects and causes of gene mutations
  • The regulation of gene expression
  • Genetic physical traits
  • The impact of environmental factors on trait expression

Convenience is a key component of this prep chapter; you can use a computer, smartphone or tablet to complete the lessons. Take a practice quiz after each lesson to confirm your understanding of the material.

What Is a Gene? - Definition & Structure

1. What Is a Gene? - Definition & Structure

Genes are little codes found in our cells that make up who we are. This lesson covers where genes are located, how we get our genes, and the functions of genes.

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

2. 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.

Mutations: When DNA Is Copied Wrong

3. Mutations: When DNA Is Copied Wrong

In this lesson, we will learn how mutations, or errors in DNA, come about, what kinds of effects they may have, and how they can impact populations as a whole.

Regulation of Gene Expression: Transcriptional Repression and Induction

4. Regulation of Gene Expression: Transcriptional Repression and Induction

Do our genes work the same way all the time? How do we regulate the expression of our genes? Explore the various ways organisms control gene transcription through repression and induction of operons.

Genetic Physical Traits: Definition & Examples

5. Genetic Physical Traits: Definition & Examples

This lesson describes the relationship between genetics and physical traits. It details the relationship between DNA and physical form. Also included are real-world examples, illustrations, and a brief quiz.

Gene-Environment Interaction

6. Gene-Environment Interaction

The following lesson explores how genes and a person's environment influence behavior and outward expression of traits. A short quiz will follow the lesson to check your understanding of this timely topic.
