Ch 10: DNA: The Basis of Inheritance

About This Chapter

The DNA: The Basis of Inheritance chapter of this Cell Biology Study Guide course is the simplest way to master DNA. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of DNA.

Who's It For:

Anyone who needs help learning or mastering DNA material will benefit from the lessons in this chapter. There is no faster or easier way to learn about DNA. Among those who would benefit are:

  • Students who have fallen behind in understanding DNA
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about DNA
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the DNA: The Basis of Inheritance chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the DNA: The Basis of Inheritance chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any DNA question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:

This chapter helps students review the concepts in a DNA unit of a standard cell biology course. Topics covered include:

  • Nucleic acids and phosphodiester bonds
  • Adenine, guanine, cytosine and thymine
  • Complimentary base pairing
  • RNA
  • DNA replication
  • Helicases and DNA replication

DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

1. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.

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

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

Learn the language of nucleotides as we look at the nitrogenous bases adenine, guanine, cytosine and thymine. Armed with this knowledge, you'll also see why DNA strands must run in opposite directions.

DNA: Discovery, Facts, Structure & Function in Heredity

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

This lesson will help you to navigate the twists and turns of DNA's structure. We'll also clue you in on the amazing discoveries that put this nucleic acid in the limelight as the molecule of heredity.

Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

4. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.

What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

5. What Is DNA Replication? - Conservative, Semi-Conservative & Dispersive Models

How do we know that DNA replication is semi-conservative? How do we know it's not conservative or dispersive? Let's follow the famous experiment by Meselson and Stahl to find out!

How Helicase Unwinds the DNA Double Helix in Preparation for Replication

6. How Helicase Unwinds the DNA Double Helix in Preparation for Replication

How does semi-conservative replication begin? Discover how DNA helicase creates a replication fork to unwind the complicated DNA molecule and allow daughter strands to form on the parental template.
