Ch 16: Campbell Biology Chapter 16: The Molecular Basis of Inheritance

About This Chapter

The Molecular Basis of Inheritance chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with the molecular basis of inheritance. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Molecular Basis of Inheritance textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Molecular Basis of Inheritance chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the molecular basis of inheritance topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The double helix structure of DNA
  • The names of the nitrogenous bases in DNA
  • The process of DNA replication
  • What happens during DNA mismatch repair
  • How DNA double-strand breaks are fixed

Test your knowledge with a 30-question chapter practice test
DNA: Discovery, Facts, Structure & Function in Heredity

1. DNA: Discovery, Facts, Structure & Function in Heredity

The discovery of DNA is the foundation of all research in molecular biology. Learn the facts about the discovery of DNA, its structure, and the function of DNA in heredity.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing

2. DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing

The four nitrogenous bases found is DNA are adenine, guanine, cytosine and thymine. Discover the base pairs of these nitrogenous bases and why DNA strands are antiparallel.

DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

3. DNA Replication: Review of Enzymes, Replication Bubbles & Leading and Lagging Strands

Enzymes, parent strands, and daughter strands are parts of the process of DNA replication. Learn about the parts of DNA replication, including enzymes, replication bubbles, and leading and lagging strands.

DNA Mismatch Repair: Correcting Errors That Happen During DNA Replication

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

DNA mismatch repair machinery, a natural process in living organisms, is responsible for identifying and correcting DNA replication errors. Explore DNA mismatch repair, learn how cells recognize errors and the parental strand, and understand how cell mutations can lead to cancer when mismatch repair is not working.

DNA Repair: Fixing Double-Strand Breaks

5. DNA Repair: Fixing Double-Strand Breaks

DNA has two strands and either one or both can be broken and also repaired within a cell. Learn the two ways cells fix DNA double-strand breaks, including homologous recombination with sister chromatids, which are exact copies of chromosomes cells use to replicate DNA, or using a different method called non-homologous end-joining.
