11 Lessons in Chapter 11: AP Biology - DNA and RNA: Homework Help
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.

Adenine: Structure, Overview

5. Adenine: Structure, Overview

Adenine is an important building block for life. Without it, we wouldn't have DNA, RNA, or ATP. In this lesson, gain an understanding of this important molecule.

DNA Ligase: Definition & Role

6. DNA Ligase: Definition & Role

You will learn how everything comes together at the end of DNA replication through the actions of DNA ligase. Once you think you know the lesson, then take the quiz to check your understanding.

DNA Sequencing: Definition, Methods & Applications

7. DNA Sequencing: Definition, Methods & Applications

DNA sequencing allows scientists to know the exact message coded in DNA. In this lesson, we'll talk about how DNA replication is the basis for sequencing, how scientists do DNA replication in the lab, and important uses for it in research and everyday life.

Primase: Definition & Function

8. Primase: Definition & Function

Primase is a really important part of DNA replication. In this lesson, you'll learn about DNA replication, the role primase plays in it, and why primase is necessary.

Sticky Ends of DNA: Definition & Concept

9. Sticky Ends of DNA: Definition & Concept

Different pieces of DNA can be cut and pasted together in order to make recombinant DNA. This lesson will describe how sticky ends of DNA are used to do this and will test your understanding with a quiz.

What are Purines? - Definition & Explanation

10. What are Purines? - Definition & Explanation

In this lesson, you will learn what purines are, how to distinguish them from other molecules, and why purines are so important in biological systems. A quiz at the end of the lesson will test your knowledge.

High-Throughput Sequencing of DNA

11. High-Throughput Sequencing of DNA

New sequencing methods have revolutionized the study of genomes. Find out how new technology and computer power are enhancing our understanding of genomes worldwide.
